We are running the python API to retrieve build info:

build_info = server.get_build_info(job, build)

and getting invalid json back (json.decoder.JSONDecodeError: Unterminated string)

It seems that the build data returned by the API is just abruptly cut off. We are using LDAP authentication and see an error in the logs (traceback below) indicating that a user is "administratively disabled"

In the build directory for our job we see that the user is in a changelog:

2210/changelog501832386212152395.xml:1180:author rinuganti@company.com <rinuganti@company.com> 2021-04-22 18:16:20 -0400

This error should be non-fatal and the REST API should return valid json. Why should every user in the changelog need to be authenticated to return the build info anyway?

We were able to work around by deleting the old builds where this user was present in the changelogs, but something isn't working and we have no way to prevent the issue from reoccurring.

TRACEBACK:
