SDK Error
ARM and Data plane OpenAPI(swagger) specs
200/201 Responses of long running operations must have a schema definition for return type. OperationId: '{0}', Response code: '{1}'
The '200'/'201' responses of the long running operation must have a schema definition.
Please refer here for details on the x-ms-long-running-operation. The '201' response code indicates 'Created' & '200' response code indicates 'Success'. In either case, it is logical for the response to be the same.
Ensure that the '200'/'201' responses of the long running operation has a schema definition. This might involve a service side change which will result in a breaking change in the generated SDK.
