Python API fails on a call to /api/v2/reflection/api-methods with "Can not find message descriptor by type_url: type.googleapis.com/ApiListApproverSuggestionsArgs"

See original GitHub issue

This is a strange issue. GRR 3.2.4.5.

curl -v http://localhost:8000/api/v2/reflection/api-methods results in this:

> GET /api/v2/reflection/api-methods HTTP/1.1
> Host: localhost:8000

{"items": [{"category":

note the )]}' returned as the first 4 bytes of the response. This breaks the GRR Python API client because it can’t parse the return. If I use the raw API shell, it seems to succeed.

Any idea what’s going on here?

Sure, glad I could help 😃 We should output a warning message in the grr-api-client if we detect a newer server version (created an issue for this: https://github.com/google/grr/issues/686).

Aha, I upgraded the server to 3.2.4.6 but didn’t think about the Python library. I was running:

grr-api-client==3.2.4.post3
grr-response-proto==3.2.4.post3

upgrading to grr-api-client-3.2.4.post6 resolved it.

Thanks for the handholding. 😉
