TL;DR

Fix the stream state handling in the source: an incremental Airbyte sync that ends without a state message cannot resume safely, so check the source state emission at the end of each stream and upgrade or patch the connector that drops it. Airbyte treats the state message as the bookmark for incremental syncs. A sync that reads records but emits no state forces the next run to start over or fail the connection check that validates state.

airbyte connection check failed error "state message missing for incremental sync"

Use this when

• The check or run fails with this symptom: an Airbyte connection check fails with state message missing for incremental sync.
• You are working on an Airbyte connection using an incremental source connector, often a custom or low-code connector and the failure repeats on the same data or configuration.
• You need the failing rows, rule, or stage isolated before changing thresholds or code.

Not for this skill when

• A full refresh connection, where no state message is expected and the failure lies elsewhere.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Open the sync logs and find the last messages emitted for the failing stream. Verify: records were emitted but no state message follows them
2. Check the connector version and whether the stream declares incremental support with a cursor field. Verify: the stream cursor configuration is confirmed
3. For a custom connector, emit a state message with the cursor value at the end of each stream read, following the Airbyte protocol. Verify: a test read shows records followed by a state message
4. For a marketplace connector, upgrade to a version that emits state for that stream, or switch the stream to full refresh as a stopgap. Verify: the connection check passes
5. Run a full sync and then a second incremental sync. Verify: the second sync starts from the saved cursor and reads only new records

Variant phrasings

airbyte state message missing incremental sync

The shorter phrasing focused on the named failure.

airbyte connection check failed state message

The symptom phrasing a searcher tries next.

airbyte incremental sync state missing fix

The variant naming the failing stage or tool directly.

Compatibility: Airbyte protocol 0.2 and later, source connectors with incremental streams

Why it happens

State emission is the connector job, and some custom or older connectors finish a read without writing the final state, especially when a stream returns zero records or ends on an error path. The platform then has records with no bookmark and fails validation.

Edge cases / pitfalls

• A stream that returns zero new records still must emit state; the empty case is where custom connectors most often skip it.
• Switching to full refresh hides the bug and multiplies cost on large streams; treat it as a stopgap with a date, not the fix.

TL;DR

Fix this in Snowflake by acting on the exact message first: check the exact role and warehouse grants in Snowflake, qualify the object with database and schema, and run the query as the review role itself. 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.

when agent tried to query Snowflake metrics it failed with connection error failure

Use this when

• The operation in Snowflake fails with this exact message: when agent tried to query Snowflake metrics it failed with connection error failure.
• 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 Snowflake, 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: check the exact role and warehouse grants in Snowflake, qualify the object with database and schema, and run the query as the review role itself. Verify: confirm the query returns rows when run as the review role.
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. Rerun the original operation in Snowflake 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, decisions or alerts against the source in Snowflake 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 error, the fix applied and the evidence of success.

Why it happens

Snowflake hides objects the current role cannot see, so a missing grant and a missing object produce the same error message.

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

Snowflake 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: Snowflake 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

An Airbyte row count anomaly usually sits in the sync, not the check: open the sync history for the affected stream, compare source and destination counts per stream, and look for a reset, a schema change, or a cursor that stopped advancing. Fix the sync configuration or run a targeted backfill for the stream, then let the check re-evaluate.

how to fix row count anomaly failure error in airbyte sync data quality check

Use this when

• The check or run fails with this symptom: the data quality check on an Airbyte-synced table reports a row count anomaly.
• You are working on an Airbyte sync whose destination row counts trip the quality check and the failure repeats on the same data or configuration.
• You need the failing rows, rule, or stage isolated before changing thresholds or code.

Not for this skill when

• A check failing on a non-Airbyte pipeline, where sync history and cursors do not apply instead.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Open the Airbyte sync history for the stream and record attempts, rows emitted, and any resets in the anomaly window. Verify: the sync history for the window is documented
2. Compare per-stream source counts with destination counts to isolate whether one stream or the whole connection drifted. Verify: the anomaly is scoped to a stream or the connection
3. Inspect the stream's cursor field and schema for changes that would stall or duplicate extraction. Verify: cursor and schema state are checked
4. Fix the configuration, clear a stuck cursor deliberately, or run a backfill for the affected window, documenting any reset's impact. Verify: the sync is corrected or the backfill is running with a known scope
5. After the sync completes, reconcile counts again and rerun the quality check. Verify: counts reconcile and the check passes

Variant phrasings

row count anomaly airbyte sync data quality

The verbatim Airbyte anomaly phrasing.

airbyte stream row count mismatch destination

The reconciliation phrasing for per-stream counts.

airbyte cursor stuck row count check failed

The cursor phrasing for stalled extraction.

Compatibility: Airbyte syncs with destination data quality checks on row counts

Why it happens

Airbyte moves data stream by stream with cursors, so a stalled cursor, a stream reset, or a source schema change alters destination counts in ways that look like data anomalies downstream. The quality check sees the destination only; the sync history holds the explanation.

Edge cases / pitfalls

• Resets re-sync full history and can duplicate if the destination write mode is append. Confirm the write mode first.
• Alert per stream, not per connection. One sick stream hides inside a healthy connection total.
