parser failed on moderation action log for exporting monthly moderation metrics error parsing failure

TL;DR

Fix this in moderation action log by acting on the exact problem first: inspect the log format for a new action type or a changed column order since last month, update the parser mapping for that change, rerun on this month file, and verify totals for one action type by counting it in the source log by hand. Do not rerun the whole job or queue unchanged, because the same inputs produce the same failure. Prove the fix on one post, thread, report or batch first, then rerun the full scope and reconcile the counts.

Use this when

• The operation in moderation action log fails with this exact message or symptom: parser failed on moderation action log for exporting monthly moderation metrics.
• The same failure repeats on retry with unchanged inputs.
• Moderation, routing, auditing or a member facing community task 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 problem remains.
• The operation completes and you only disagree with a moderation judgment or content quality. That is a policy review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in moderation action log, and copy the full message plus the post, thread, report or member involved into the run notes. Verify: the problem is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this problem: inspect the log format for a new action type or a changed column order since last month, update the parser mapping for that change, rerun on this month file, and verify totals for one action type by counting it in the source log by hand. Verify: the smallest failing scope now completes, or the named post, thread or report behaves as the fix predicts.
3. Check the neighbouring posts, threads, reports or members that share the same setting, rule or workflow, 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 moderation action 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.
5. Compare the result counts or status against the source in moderation action log 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 problem, the fix applied and the evidence of success.

Why it happens

Platforms add action types and reorder export columns quietly, and a parser built for last month shape fails or silently misreads the new one.

The verbatim form searchers paste from the console, queue or report. Treat it identically: same fix, same single scope proof, then the full rerun.

How to fix - parser failed on moderation action log for exporting monthly moderation metrics error parsing failure

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

moderation action log 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.

Edge cases

• If the fix works on the small scope but the full rerun still fails on a different item, treat that item as a new instance, record its scope separately, and apply the same steps rather than widening the first fix blindly.
• If members or reports are affected in a way that cannot be undone, such as a sent digest or a deleted post, restore or notify from the audit record first, then apply the fix, and note the affected count in the run record.
• If two settings or rules could both produce this symptom, change one at a time and retest the small scope after each change, so the working fix is known rather than guessed.

Compatibility: moderation action log at current versions, plus the admin console, moderation queue or API the query names; no extra tooling beyond the source system access needed to verify counts.
