Suddenly, when using the "Github Commiter" authorization strategy, we're getting an exception. From the log:

WARNING: Caught exception evaluating: it.items in /. Reason: java.lang.reflect.InvocationTargetException
...
Caused by: java.util.concurrent.ExecutionException: java.io.FileNotFoundException: https://api.github.com/repos/[redacted]/collaborators

The API endpoint returns:

{
"message": "Not Found",
