agent timed out when agent tried to validate synthetic data output err

Not specified by the original author.

TL;DR

Fix this in synthetic data agent workflow by acting on the exact message first: validate in layers, run fast schema and count checks on the full output, then run expensive distribution and privacy checks on a stated sample, saving each layer result before the next begins. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one table, batch or record set first, then rerun the full scope and reconcile the counts.

agent timed out validating synthetic data output

Use this when

• The operation in synthetic data agent workflow fails with this exact message or symptom: agent timed out validating synthetic data output.
• The same failure repeats on retry with unchanged inputs.
• Generation, validation or export 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 error remains.
• The operation completes and you only disagree with its output quality. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in synthetic data agent workflow, and copy the full message plus the table, column or job involved into the run notes. Verify: the error is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this error: validate in layers, run fast schema and count checks on the full output, then run expensive distribution and privacy checks on a stated sample, saving each layer result before the next begins. Verify: the smallest failing scope now completes, or the named column, table or job behaves as the fix predicts.
3. Check the neighbouring tables, columns or jobs that share the same config, schema 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 synthetic data agent workflow 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, distributions or status against the source in synthetic data agent workflow 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

Running every expensive validation over the full output in one step exceeds timeouts that a layered pass, cheap checks everywhere and deep checks on a sample, fits comfortably.

How to fix - agent timed out when agent tried to validate synthetic data output error failure

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

synthetic data agent workflow 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: synthetic data agent workflow at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.

TL;DR

Fix this in synthetic data agent workflow by acting on the exact message first: replace full pairwise privacy checks with sampled distance checks first, compute nearest neighbour distances in batches saved to disk, and widen to the full check only for the columns the sampled check flags. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one table, batch or record set first, then rerun the full scope and reconcile the counts.

agent timed out validating synthetic data privacy

Use this when

• The operation in synthetic data agent workflow fails with this exact message or symptom: agent timed out validating synthetic data privacy.
• The same failure repeats on retry with unchanged inputs.
• Generation, validation or export is blocked until this item completes.

Why it happens

Pairwise distance privacy metrics scale quadratically, so a full check inside one agent step times out on datasets that sampled checks assess reliably.

TL;DR

Fix this in synthetic data agent workflow by acting on the exact message first: cap the QA sample at a stated size such as one thousand records, request the sample with pagination or a limit argument instead of materialising the full dataset, and cache the sample file for the whole QA pass. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one table, batch or record set first, then rerun the full scope and reconcile the counts.

Why it happens

Sampling without a limit often materialises or scans the entire dataset first, which turns a quick QA draw into a full table operation that times out.
