parser failed on Fireflies JSON transcript speaker array empty after diarization

TL;DR

Fall back to the transcript text and timestamps in the JSON when the speaker array is empty, assign a single unknown speaker rather than aborting, and flag the call for re-diarization instead of dropping it from the summary queue. Start with the Fireflies JSON transcript for the call, its empty speaker array, and the same call viewed in the Fireflies app, work on one affected call, record, or run first, and prove the fix there before running the full set. Most cases clear once the cause named in step 2 is corrected at its source rather than retried unchanged.

Use this when

• You see this exact message or symptom: parser failed on Fireflies JSON transcript speaker array empty after diarization
• One run, record, call, or object is affected and you can name it
• A retry without changing anything reproduces the same result

Not for this skill when

• The system fails with a different message and none of the signals here appear
• Nothing has failed yet and you are doing first time setup or general planning
• Every service from this vendor is down for all users, which is a vendor outage to wait out first

Steps

1. Reproduce the failure once using the Fireflies JSON transcript for the call, its empty speaker array, and the same call viewed in the Fireflies app, and record the time, the workspace or account, and the one item it names. Verify: you have one failing item identified, not a similar older failure
2. Inspect whether text segments exist while speaker entries are empty, and whether the app view shows speaker labels the export lost. Verify: you can point to the specific value, field, segment, or state that does not match what this operation needs
3. Apply the fix at that source: fall back to the transcript text and timestamps in the JSON when the speaker array is empty, assign a single unknown speaker rather than aborting, and flag the call for re-diarization instead of dropping it from the summary queue. Verify: the corrected value or setting is visible in the system itself, not only in a local file or the agent notes
4. Re-run the original operation on the single affected item first. Verify: that one item completes with no trace of the failure described above, and the call summarizes from its text segments and is listed for re-diarization rather than missing
5. Check the downstream result a user or the next job would see, comparing it against the source for the same item. Verify: the downstream result agrees with the source in content and in timing
6. Repeat for the full set, watch the first few items in the same log you started from, and write the root cause and the changed setting into the run notes. Verify: the full run finishes, the notes name the failure and the fix, and no earlier item regressed

Variant phrasings

parser failed on Fireflies JSON transcript speaker array empty after diarization

The subject-first phrasing of the same failure. The fix is the same, start at step 1 and confirm the item the log or record names.

Tool-first phrasing of this failure

The phrasing searchers use once they know which system raised it. It is the same underlying problem, not a separate bug.

Why does this keep happening after a retry

The repeat-occurrence phrasing. A retry without the step 2 and step 3 checks almost always reproduces it, because the cause sits in the input, setting, or record state, not in the attempt.

Compatibility: Parsers handling Fireflies JSON transcripts, at current versions

Why it happens

A diarization failure can leave the export with text but an empty speaker array, and a parser that requires speakers before reading text discards a usable transcript.
