## TL;DR
Fix this by acting on the exact problem first: run the insurance certificate scan again on a clean, straight and high resolution copy of the certificate, check that the expiry date, insured name and policy type fields are read correctly on that one file, and only then use the parsed values to check a vendor score change after new findings. Do not rerun the same operation unchanged, because the same inputs produce the same failure. Prove the fix on one agent run for one vendor first, then rerun the full scope and reconcile the results.

## Use this when
- The operation in the insurance certificate parser fails with this exact problem: parser failed on insurance certificate scan for check a vendor score change after new findings error parsing failure.
- The same failure repeats on retry with unchanged inputs.
- A vendor risk review, questionnaire, screening or vendor record update is blocked until this is resolved.

## Not for this skill when
- The notice is a platform outage from the vendor. Resolve that first, then return here if this problem remains.
- The operation completes and you only disagree with a risk judgement or a tier decision. That is a risk owner decision, not this failure.

## Steps
1. Reproduce the failure on one named agent run for one vendor in the insurance certificate parser and record the full problem text plus the vendor, record or report involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: run the insurance certificate scan again on a clean, straight and high resolution copy of the certificate, check that the expiry date, insured name and policy type fields are read correctly on that one file, and only then use the parsed values to check a vendor score change after new findings. Verify: the single failing agent run for one vendor now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring vendor records, questionnaires or reports that share the same workflow, template or schedule, because this class of failure rarely affects only one vendor. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in the insurance certificate parser on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
5. Compare the result against the source of truth, the vendor supplied document, the questionnaire response or the risk record, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the vendor record or review log so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

## Variant phrasings

### parser failed on insurance certificate scan for check a vendor score change after new findings error parsing failure
The verbatim form searchers paste from the console, report or run log. Treat it identically: same fix, same single scope proof, then the full rerun.

### How to fix - parser failed on insurance certificate scan for check a vendor score change after new findings error parsing failure
The how to phrasing for the same failure in the insurance certificate parser. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### The insurance certificate parser troubleshooting for this failure
The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

## Why it happens
Certificate parsers fail on low quality scans, rotated pages and image only files that contain no readable text layer, so the extraction returns an error or empty fields even though a person can read the certificate clearly.

## Edge cases
- The vendor record, questionnaire version or portal page changed after the failing run started. Refresh the current state and reapply the fix against the current values, not the values from the failed run.
- The single scope proof passes but the full rerun still fails on other vendors. Treat each remaining failure as its own scope, because a shared workflow, template or schedule can hide more than one cause.
- The source systems disagree on the correct value. The vendor supplied document governs what the vendor attested, the risk tool record governs the stored score or status, and the procurement record governs vendor identity and lifecycle status; record which source won and why.

Compatibility: The insurance certificate parser at current versions, plus the vendor risk, procurement or source system the query names; no extra tooling beyond access to the source records needed to verify results.
