500 error for the Mouser provider

Part-DB
Version: 2.4.0

Hi Part-DB team,

I can reproduce a 500 error for the Mouser provider in “Create part from information source”.

From the Part-DB container logs, Part-DB calls:
POST https://api.mouser.com/api/v2/search/keyword?apiKey=

Mouser responds with HTTP 200 but with an error JSON payload:
{"Errors":[{"Code":"Invalid","Message":"Invalid unique identifier.","PropertyName":"API Key"}],"SearchResults":null}

Part-DB then throws a RuntimeException and returns 500:
RuntimeException: "Unknown response format: {"Errors":[...],"SearchResults":null}"
at MouserProvider.php:232 (responseToDTOArray)

Log excerpt (sanitized):

• Request: POST https://api.mouser.com/api/v2/search/keyword?apiKey=
• Response: 200 ...
• Exception: Unknown response format ... PropertyName: "API Key"

Reproduction / verification from the same container network

1. Extract the last Mouser URL from logs:
   URL="$(sudo docker logs --tail 5000 partdb 2>&1 | grep -oE 'https?://api.mouser.com[^\" ]+' | tail -n 1)"

2. Confirm the endpoint is POST-only:
   sudo docker run --rm --network container:partdb curlimages/curl:8.5.0 -sS -I "$URL"
   -> HTTP 405
   sudo docker run --rm --network container:partdb curlimages/curl:8.5.0 -sS "$URL"
   -> {"Error":{"Code":"UnsupportedApiVersion","Message":"... does not support HTTP method 'GET'."}}

3. POST to the same endpoint yields HTTP 200 with an error JSON (when the API key/request is not accepted):
   PAYLOAD='<(ideally the exact JSON payload that Part-DB sends)>'
   sudo docker run --rm --network container:partdb curlimages/curl:8.5.0
   -sS -X POST -H "Content-Type: application/json" --data "$PAYLOAD" "$URL" | head -c 800

Expected behavior

• If Mouser returns Errors[] (even with HTTP 200), Part-DB should surface a provider-level error message (e.g. invalid API key / invalid request) and not crash with a 500 “unknown response format”.

Thanks!

I think it's a shame that no one responds to error messages here. If you don't have the time or inclination, then you just have to give up on the project, but having over 30 open errors is not okay.

What is the content of the json that the Mouser API returned? It says "Property: APIKey" which implies that your API key is invalid. You should double check if it is correct. I can reproduce the behaviour when providing a random string as the Mouser API key.

Technically, one could also argue that Mouser should not return 200 when the user provides invalid credentials...but that's another story. In general, I agree that the error should be handled and displayed more user friendly.

As far as I know, Part-DB is maintained by a single person (because you addressed a team in your issue).
Other users (like me for example) try to help out in the best of our beliefs and abilities.

As the error message seems to suggest an invalid API key, and nobody can reproduce this error im closing this issue.
