Label Studio API rate limit hit mid-import failed with 429 error

Not specified by the original author.

TL;DR

Fix this in Label Studio by acting on the exact message first: honour the Retry-After header, add exponential backoff with jitter, and checkpoint progress so a throttled run resumes instead of restarting. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

Label Studio API rate limit hit mid-import failed with 429 error

Use this when

• The operation in Label Studio fails with this exact message: Label Studio API rate limit hit mid-import failed with 429 error.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Label Studio, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: honour the Retry-After header, add exponential backoff with jitter, and checkpoint progress so a throttled run resumes instead of restarting. Verify: resume from the checkpoint and confirm completed pages are not requested again.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in Label Studio so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in Label Studio 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.
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 error, the fix applied and the evidence of success.

Why it happens

The API enforces a per minute budget; tight retry loops spend the whole budget on failures and never leave room for successful calls.

How to fix: Label Studio API rate limit hit mid-import failed with 429 error

The how-to phrasing for the same failure in Label Studio. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Label Studio 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.

Compatibility: Label Studio at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.

TL;DR

Import in rate-shaped batches with a checkpoint: the remaining runs were abandoned because the import treated the 429 as a run failure instead of a pacing signal. Keep an import ledger of run ids completed, sleep for the rate window when limited, and resume with only the unimported runs, verifying the final count against the sweep's run list.

W&B API rate limit hit mid-sweep import and agent failed to import remaining runs with 429 error

Use this when

• The run or call fails with this symptom: W and B API rate limit hit mid-sweep import and the agent failed to import remaining runs.
• You are working on an agent importing sweep runs into W and B or mirroring them elsewhere and the failure repeats on the same run or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A rate limit imposed by account tier that no pacing can satisfy for the volume, where the fix is splitting the import across days or raising the tier.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Build the authoritative list of sweep runs to import and mark each as imported or pending in a ledger. Verify: import state exists per run
2. On a 429, pause for the window the API indicates instead of marking runs failed, then continue from the ledger. Verify: rate limits pause rather than abort the import
3. Process imports in fixed-size batches sized to stay under the account's request budget. Verify: batch pacing keeps the rate under the limit
4. At the end, diff the ledger against the sweep's run list and import any stragglers before reporting completion. Verify: the final counts match the sweep exactly

wandb api rate limit mid sweep import remaining runs

The verbatim phrasing.

agent import sweep runs 429 resume ledger fix

The ledger phrasing.

wandb sweep import incomplete rate limited agent

The incomplete phrasing.

Compatibility: Weights and Biases API driven by agents during sweep imports

Why it happens

Sweep imports are bursty: hundreds of runs arrive at once and each takes several API calls. Without a ledger, a mid-import limit strands the tail invisibly, because the imported prefix looks like a complete, if smaller, sweep.

Edge cases / pitfalls

• Runs imported partially, metadata without history, need the ledger at field granularity for the worst cases.
• Mirror the sweep's own pagination discipline; the source list and the import both need completeness checks.
