agent failed to detect a0deploy partial import error tenant half applied

Not specified by the original author.

TL;DR

Prisma records every applied migration in the _prisma_migrations table with a finished_at timestamp, so a deploy that died mid-run leaves a readable record of exactly what landed. Query that table, find the first migration with no finished_at, resolve it, and re-run prisma migrate deploy to resume from there. Never edit migration history rows by hand.

The query

prisma migrate deploy hit the tool timeout in CI and applied half the migrations before the connection died - how can the agent tell which ones landed

Use this when

• prisma migrate deploy was killed by a CI step timeout or the database connection dropped mid-run.
• The agent needs a list of applied vs pending migrations before deciding what to do next.
• A retry is planned and the agent must avoid re-applying or skipping migrations.

Not for

• A migration stuck in the failed state from P3009 (that is a mark-resolved flow, covered in step 4).
• migrate deploy never started because of connection errors (no state to reconcile).
• The migration history table was hand-edited and checksums disagree.

Steps

Step 1: Read the migration state from the database

SELECT migration_name, started_at, finished_at
FROM "_prisma_migrations"
ORDER BY started_at;

Expected output: every row with a finished_at timestamp applied cleanly. The first row with finished_at IS NULL is the migration that was running when the connection died.

Step 2: Confirm the history is clean with migrate status

npx prisma migrate status

Expected output: migrate status lists which migrations are pending. If it reports a checksum or drift error instead, stop and fix that first. The resume path only works on a clean history.

Step 3: Inspect the in-flight row

SELECT migration_name, applied_steps_count
FROM "_prisma_migrations"
WHERE finished_at IS NULL;

Expected output: zero or one row. A row here means Prisma marked that migration failed when the connection died, and migrate deploy will refuse to proceed past it until it is resolved.

Step 4: Resolve the failed row according to what actually ran

npx prisma migrate resolve --rolled-back "[failed migration name]"

Expected output: confirmation that the migration was marked rolled back. Choose rolled back when the migration did not fully apply. Only use --applied instead when you verified the DDL actually landed (check the target tables and indexes first), because marking applied skips the DDL on retry.

Step 5: Resume the deploy

npx prisma migrate deploy

Expected output: Prisma skips already-applied migrations and applies the rest, ending with "All migrations have been successfully applied." Confirm the exit code is 0 before the CI step ends.

Step 6: Verify the schema matches the migration set

npx prisma migrate status

Expected output: migrate status shows no pending migrations. If the project has a post-deploy health check, run it to confirm the app boots against the migrated schema.

Variant phrasings

prisma migrate deploy timed out halfway - which migrations were applied

Same _prisma_migrations reconciliation. Steps 1-3 give the applied list, steps 4-5 resume.

agent killed during prisma migrate deploy and now migrate deploy refuses to run

The killed migration is in the failed state. Step 4 resolves it before step 5 resumes.

how to resume prisma migrations after the CI connection dropped

Re-run migrate deploy after resolving any failed row. Prisma picks up where the history table says it stopped.

Why it happens

Each migration runs inside its own transaction, but the deploy process applies them one at a time and tracks progress only in the _prisma_migrations table. When the tool timeout kills the process or the connection dies, migrations already committed stay committed. Only the in-flight one is left unmarked. The agent's job is not to guess what landed. The history table already says. The job is to resolve the in-flight row and re-run the same command.

Edge cases

• Do not delete rows from _prisma_migrations to "reset" state. Every fresh environment will then fail checksum validation.
• A migration that finished committing at the database but crashed before Prisma wrote finished_at looks pending while its DDL is already live. Check the actual tables before choosing rolled-back vs applied.
• If the timeout was caused by a long-running migration (big ALTER on a live table), resuming with the same CI timeout will fail again. Raise the timeout or run the heavy migration separately.
• Do not run migrate dev in CI to recover. It can reset the database. migrate deploy is the only safe resume command.
• Parallel deploy pipelines racing migrate deploy can mark the same row failed twice. Serialize deploys with a lock.

Fix the onboarding agent timing out on a 10k-row HR CSV and leaving half-provisioned users

TL;DR

Split the import into small committed batches with a durable checkpoint after each one, and run it as a background job that can resume. A 10k-row import is not one action; it is hundreds of small ones. Timeouts are inevitable at that scale, so the import must survive them instead of fearing them.

The problem

import: 10,000 rows, single synchronous run
result: timed out at row 4,812 after 30 minutes
state: 4,812 users created, 5,188 missing, no record of where it stopped
retry: starts at row 0, duplicates the first 4,812

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=onboarding agent timed out 10k row hr csv left half-provisioned users"

Fix it

Step 1: Chunk the file into small batches

Split the CSV into batches of 100 to 200 rows. Each batch is an independent unit of work with its own commit and its own confirmation.

Expected: no single unit of work runs long enough to hit a timeout.

Step 2: Checkpoint after every committed batch

Write the last committed row number to durable storage after each batch confirms. The checkpoint must survive the agent crashing, the VM restarting, and the run being killed.

Expected: a crash at any point leaves an exact resume position.

Step 3: Run the import as a resumable background job

Move the import out of the interactive agent turn into a background job that processes batches and updates the checkpoint. The agent monitors progress; it does not hold the whole import in one turn.

Expected: timeouts of the agent turn no longer affect the import at all.

Step 4: Make every create idempotent

Key each user create on a stable id from the CSV (employee id or email) and check existence before creating. A resumed batch that replays a row must not duplicate it.

Expected: re-running any batch is safe, including the batch that was in flight during the crash.

Step 5: Prove resume works by killing it mid-run

Start the import in staging, kill the job at 40 percent, and resume.

Expected: the import completes with zero duplicates, zero skipped rows, and the final checkpoint matches the row count.

When this applies

• Large CSV imports time out partway and leave partial user sets
• The retry restarts from the top and duplicates early rows
• The import runs inside a single agent turn with a time limit

When it doesn't

• The CSV fails to parse (fix the parser first)
• The source data has duplicate rows (dedupe the file first)
• A small import fails on every row (a per-row bug, not a scale problem)

Compatibility

HR CSV imports into Okta, Entra ID, Google Workspace, and BambooHR-style sources; any batch user creation the agent performs at scale.

Variant phrasings

hr import timed out halfway thousands of users

Same fix. The timeout is a scale fact; the missing checkpoint is the bug.

bulk user import left half the users unprovisioned

Reconcile first: diff the CSV against the created users to find the exact gap, then resume from the checkpoint.

Why it happens

Agents process files the way they read them: start at the top, work down, finish. That works for 50 rows. At 10k rows the run outlives every timeout in the stack - the agent turn, the HTTP request, the function limit - and it always dies in the middle. Without a checkpoint the only recovery is starting over, and without idempotent creates starting over means duplicates. The import was designed for the happy path at a scale where the happy path never happens.

Edge cases

• The CSV changes between runs: hash the file and refuse to resume on a different hash
• Rows near the crash may have been sent but not confirmed: idempotent creates make replay safe
• Rate limits on the target API: pace batches so the import does not 429 itself to death

If it still fails

• Capture the checkpoint value, the batch size, and the row range of the failed batch before changing anything else.
• Reproduce with a 500-row file so you are not debugging 10k rows.
• Check the target system status page; API outages look exactly like import bugs.

Prevention

• Any import over 500 rows gets chunking, checkpoints, and idempotent creates from day one.
• Progress dashboards show checkpoint vs total so stalls are visible.
• Alert when a batch job makes no checkpoint progress for 15 minutes.

TL;DR

Fix this in Conveyor import agent by acting on the exact problem first: stop the retries, split the import file into chunks under the Conveyor size limit, import one chunk and confirm it lands, then import the rest with a pause between chunks and a hard stop on any size error. Do not rerun the whole job or collection unchanged, because the same inputs produce the same failure. Prove the fix on one control, account or batch first, then rerun the full scope and reconcile the counts.

agent kept retrying oversized import file without chunking or backoff

Use this when

• The operation in Conveyor import agent fails with this exact message or symptom: agent kept retrying oversized import file without chunking or backoff.
• The same failure repeats on retry with unchanged inputs.
• An audit, evidence package or compliance review is blocked until this item completes.

Not for this skill when

• The message is an outage notice from the platform. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with an auditor judgment or a control design choice. That is a review discussion, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Conveyor import agent, and copy the full message plus the control, account or item involved into the run notes. Verify: the problem is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this problem: stop the retries, split the import file into chunks under the Conveyor size limit, import one chunk and confirm it lands, then import the rest with a pause between chunks and a hard stop on any size error. Verify: the smallest failing scope now completes, or the named control, account or item behaves as the fix predicts.
3. Check the neighbouring controls, accounts or items that share the same connection, mapping or owner, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in Conveyor import agent on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts or status against the source in Conveyor import agent so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

Why it happens

A size rejection never succeeds on retry with the same file, and each blind retry wastes the import window while teaching the agent nothing about the limit it hit.

Variant phrasings

The verbatim form searchers paste from the console, ticket or audit request. Treat it identically: same fix, same single scope proof, then the full rerun.

How to fix - agent kept retrying Conveyor import with oversized file without chunking or backoff

The how to phrasing for the same failure in Conveyor import agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Conveyor import agent troubleshooting for this failure

The symptom first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Edge cases

• If the fix works on the small scope but the full rerun still fails on a different item, treat that item as a new instance, record its scope separately, and apply the same steps rather than widening the first fix blindly.
• If evidence was already sent to an auditor in the wrong state, correct the record with a dated note explaining what changed, rather than silently replacing files in the package.
• If two settings or mappings could both produce this symptom, change one at a time and retest the small scope after each change, so the working fix is known rather than guessed.

Compatibility: Conveyor import agent at current versions, plus the admin console or API the query names; no extra tooling beyond the source system access needed to verify counts.
