Additional troubleshooting steps to try when getting random error in UI.
Receiving random UI error when trying to perform an operation.
Open browser in incognito or private mode. Try to perform the same operation again in the UI and see if error returns. If error does not then try clearing browser cache, cookies, and history. May need to reboot PC also as an additional troubleshooting step.
If after reboot the issue still persists perform same operation on another PC. If after performing these different steps the error in UI still persists please contact support.
