I’m experiencing an issue with the OAuth Refresh Token connector. It does not seem to function well in Universal or as a scheduled system flow.

When changing the system flow and adding a table task to manually trigger the flow in the Windows GUI I successfully get a new access token with the current refresh token.

But when I manually trigger the flow from the Universal GUI, or let the system flow run automatically (after changing it back to a system flow by removing the table task) in the background it fails. It seems like it can’t find the client_id, even though the OAuth Server seems to be configured correctly (It works in the Windows GUI after all).

This is the errors I get in the Universal Indicium log:

My OAuth Server configuration in the SF (I have the same config for both the DEV and TEST branches):

My OAuth Server configuration in IAM:

I first thought it was because of firewalls blocking the calls on the web/indicium server. But I successfully made the calls manually through Postman on this server. The error mentioned above also suggest to me that it is not about a firewall.

I also tried changing the ‘Send client credentials’ setting to ‘As Basic Auth header’. But no luck.

For what it’s worth, we are on 2024.1.

Anybody any suggestions what it might be? What I’m doing wrong? Any input would be much appreciated.

Thanks in advance!
