agent crashed parsing a0deploy import summary error format changed

Not specified by the original author.

TL;DR: Stop regex-matching miniflare's rendered error text and read the structured error fields (name, code, message) from the caught rejection instead. Miniflare's error rendering changed across v2, v3, and the workerd-based v4, so exact-text matchers break on every upgrade while the fields stay stable.

agent parser broke on miniflare error output format change

Steps

1. Pin the miniflare version in devDependencies and record it with npx miniflare --version. Expected: one version number you can tie any parser failure to.

2. Replace exact-text matching with structural matching: catch the rejection from the request handler (dispatchFetch or the equivalent entry point) and read error.name, error.code, and error.message as fields. Expected: the parser extracts the error class even when the rendered text changes shape.

3. Keep one golden test: trigger a known error (e.g. a missing KV binding read) and assert the parser extracts its code. Expected: upgrading miniflare turns this test red before production parsers break.

4. When a break happens, diff the rendered output of the golden error between the old and new miniflare version. Expected: you see exactly which line of the format moved, and you update one matcher instead of rewriting the parser.

5. Document the miniflare version range the parser is verified against in the runbook. Expected: the next agent knows which versions are safe without re-discovering it.

Use this when

• An agent parses miniflare stderr or thrown errors and broke after a miniflare upgrade
• Error classification depends on matching rendered stack text
• Local dev uses miniflare directly rather than through wrangler dev

Not for this skill when

• The error comes from deployed workerd rather than local miniflare
• Miniflare fails to start at all (a startup problem, not a parsing problem)
• You need the full stack text for human display rather than machine parsing

Variant phrasings

• miniflare error format changed, parser no longer matches
• agent fails to classify miniflare v4 errors
• miniflare stack trace format different after upgrade
• workerd error codes not parsed from miniflare output

Why it happens

Miniflare v4 is a thin layer over workerd, while v2/v3 rendered their own error text, so prefixes, stack formatting, and how error codes surface all moved between majors. Parsers written against one version's exact wording have nothing stable to hold onto, while the underlying Error object's name, code, and message fields survive the rendering changes.

Edge cases

• Some workerd errors surface only as message text with no distinct code; keep a small allowlist of those messages as a fallback.
• Miniflare can wrap the original error in an outer error; unwrap cause chains before classifying.
• wrangler dev embeds its own miniflare version, which may differ from the standalone one you pinned; check both.
• Snapshot tests on full rendered output are brittle by design; assert on extracted fields, not on the raw text.

Thread query: agent parser broke on miniflare error output format change

TL;DR

Fix the parser for the Salesforce transcript export the agent received: validate the export shape first, then read speaker, timestamp, and text fields by name from the actual export structure (which nests utterances under call segments) instead of assuming a flat list of lines, because the export format for summarize a discovery call into Salesforce notes changed shape and the old parser failed on a good file. Start with the discovery call transcript chunks and the Salesforce note that should receive the summary, and the agent run log for the step where it stopped, 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.

parser failed on Salesforce transcript export for summarize a discovery call into Salesforce notes error parsing failure

Use this when

• You see this exact message or symptom: parser failed on Salesforce transcript export for summarize a discovery call into Salesforce notes error parsing failure
• 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 discovery call transcript chunks and the Salesforce note that should receive the summary, and the agent run log for the step where it stopped, 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 the discovery call transcript chunks and the Salesforce note that should receive the summary. 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: Fix the parser for the Salesforce transcript export the agent received: validate the export shape first, then read speaker, timestamp, and text fields by name from the actual export structure (which nests utterances under call segments) instead of assuming a flat list of lines, because the export format for summarize a discovery call into Salesforce notes changed shape and the old parser failed on a good file. 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 discovery summary sections (pain, current stack, decision process) are present in the note and match the transcript
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 Salesforce transcript export for summarize a discovery call into Salesforce notes error parsing failure

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: Salesforce exports and API at current versions, plus the CRM or sharing destination the task names; the steps assume the run can be resumed per call rather than only as a whole batch.

Why it happens

Vendor export formats drift: fields move, utterances get nested, empty calls return a different envelope. A parser written against one sample export treats the new shape as corruption, even though the transcript data inside is complete and usable.
