SAP HR Full Aggregation - ConnectorException

Hello,

We’ve been experiencing intermittent issues with full account aggregation for our authoritative source of type SAP HR/HCM. The aggregation goes down and comes back up frequently.

The error message displayed in the UI is quite generic (see screenshot below), and the ccg.log file at TRACE level doesn’t provide much more detail, only returning another generic message like "Couldn’t find message for key ‘ConnectorException’

I suspect that the issue might be caused by incorrect data for one of the users in the authoritative source.
Is there a way to further pinpoint the exact cause of this issue?

Thanks for your help.
