1. Your Integration Center Scenario is running Successfully.
2. However, in Execution Manager, you are getting a warning as below:
"ProcessDefinitionValidationException: Process Definition validation warnings - Process Definition has an Invalid operation"
Reproducing the Issue
Re-run the impacted Integration Center Scenario.
If you download the respective Integration Center Definition File, you will notice that it contains atleast one property "operation" with empty value ("operation":"").
One fix was given earlier (with b1905 Release) to avoid the failure of integration in case the operation is empty. Here, in your case, you have operation with value empty and it is just a warning and will not harm the integration flow as you can see in the Execution Manager log. So, there is NO action required for this warning as of now. You can proceed with the executions.
A fix will be applied to stop giving validation warning message in case the operation is empty, in future. No exact date time has been decided for that.
