agent couldn't parse multi-table synthetic dataset export error failed parsi

Not specified by the original author.

TL;DR

Fix this in synthetic data agent workflow by acting on the exact message first: unpack and inventory the export first, give the agent one table file at a time with its row count and header, and record the parse result per table so one bad file never blocks the readable tables. 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 could not parse multi-table synthetic dataset export

Use this when

• The operation in synthetic data agent workflow fails with this exact message or symptom: agent could not parse multi-table synthetic dataset export.
• 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: unpack and inventory the export first, give the agent one table file at a time with its row count and header, and record the parse result per table so one bad file never blocks the readable tables. 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

Handing an agent a whole multi table export at once mixes formats and sizes beyond what one parse step can handle, and the first bad file hides the good ones.

How to fix - agent couldn't parse multi-table synthetic dataset export error failed parsing 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.

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 pipeline by acting on the exact message first: parse the export table by table, list the files in the export first, detect delimiter and header per file instead of assuming one format for all tables, and log which single file fails before changing any parser setting. 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

Multi table exports mix formats, delimiters and header conventions per table, so one global parser setting inevitably fails on at least one table.

TL;DR

Fix this in synthetic data agent workflow by acting on the exact message first: identify the real file format from its first bytes and header before parsing, decompress it if it is an archive, detect encoding and delimiter from evidence, and parse a hundred rows successfully before attempting the full file. 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

Export files arrive compressed, re encoded or in a sibling format such as parquet named as csv, and parsing on assumption fails where a header inspection succeeds.
