Working in the Process Automation UI, occasionally an error message pops up that states:
An error has occurred on the server. Check the server log to see more details
However the co2.log file doesn't really have any details about what happened.
The "quick fix" for this is to just refresh your browser. The message will go away and you can continue working in the UI.
The longer fix is to increase the logging levels for Process Auto to DEBUG.
As this is a very generic message and could happen for a large number of different reasons, a support issue will be required to review the DEBUG logs to find the affected class/module.
This can be a one time issue, or it could happen several times within a single session. If it is just a one time issue, refresh your browser and you probably won't see it again.
If this does happen multiple times, and even to multiple users, please open a support issue right away so we can assist in finding a resolution for you.
