Step: Run GP Service - More info

[Ranga_Tolapi]

I have below questions regarding Run GP Service step in ArcGIS Workflow Manager v10.9.1.

1. What is the recommended GP Service type for this Step, Asynchronous or Synchronous or Both?
2. For Asynchronous GP Service, will the Step wait for GP Service to complete fully?
3. Initially configured this step with a GP Service of type Asynchronous. Later, after few jobs got created, updated GP Service type from Asynchronous to Synchronous in ArcGIS Server Manager.
   1. Noticed a SEVERE entry in the WFM logs i.e., Error performing submit job operation Error handling service request :Request type is not supported. 'SubmitJob' synchronous GP service.
   2. Anything needs to be updated/changed in the Workflow Diagram corresponding to this Step to get rid of the above error?

Highly appreciate your response.

Thank you.
