agent couldn't parse SOAR playbook run log error failed parsing failure

TL;DR

Fix this in the parser for the SOAR playbook run log by acting on the exact message first: before parsing the SOAR playbook run log, detect the log format version first, select the matching parser, and skip banner or progress lines the older parser chokes on; keep the original file untouched so the parse can be replayed. 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.

Use this when

• The operation in the parser for the SOAR playbook run log fails with this exact message: agent couldn't parse SOAR playbook run log.
• 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 the parser for the SOAR playbook run log, and copy the full message plus the alert, incident or enrichment record 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: before parsing the SOAR playbook run log, detect the log format version first, select the matching parser, and skip banner or progress lines the older parser chokes on; keep the original file untouched so the parse can be replayed. Verify: the repaired SOAR playbook run log parses end to end and the parsed record count matches the source count.
3. Check the neighbouring items that share the same config, template, feed 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 the parser for the SOAR playbook run log 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 the parser for the SOAR playbook run log 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 parser assumed a clean, current format, and the real SOAR playbook run log broke one of those assumptions, so parsing stopped at the first bad structure instead of reporting it.

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

Compatibility: the parser for the SOAR playbook run log 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.
