We are getting API version error randomly through orchestrator and need to know the reasons. Assuming, verify expression activity is throwing this error randomly.
Errors are:
Exception: Error retrieving API version: HttpOperationException : Operation returned an invalid status code ServiceUnavailable
Can anyone please support here?
can anyone help please?
Are you getting this in the test cases?
What version of robot and orchestrator you are on?
Did you happen to check the event viewer logs when this error occured?
Cheers
Yes, While executing test cases through orchestrator, we are getting it randomly.
Robot version: 21.10
Orch version: 2021.10.11

looks like an intermittent connection issue from the message…try using a retry scope around the activity and give a small delay before retry
