We're experiencing issues with new OAuth Broker API. 

In some cases it might not return the authorised credentials for a component's job. Re-running the job might be successful.

The fix will be deployed very soon.

If you haven't migrated to the new version, please wait until the fix is deployed.

We're terribly sorry for any inconvenience.
