Jira Connector - Feature Sync Failure "'reporter' cannot be set."

[#1]

Environment:
Jira Align connected and syncing with an instance of Jira.

Situation:

• A newly created Feature in Jira Align fails to create a corresponding Epic in Jira.

• The following API error is logged, revealing that there is an issue with the Reporter field:

ResponseHeader_Connection:close, ResponseContent:{\"errorMessages\":[],\"errors\":{\"reporter\":\"Field 'reporter' cannot be set. It is not on the appropriate screen, or unknown.\"}}, JsonErrors:reporter=Field 'reporter' cannot be set. It is not on the appropriate screen, or unknown

What does this mean?:

This errors typically means that Jira Align is sending Jira an API call to create an Epic and the reporter/assignee field is either not present (for the Jira Epic) or the service account the Jira Connector is using does not have permission to update the field.  

What to do?:

• Troubleshooting this will require logging into Jira as a user with Project Admin permissions.
• If the reporter field exists for the issue type, then please verify that the API Service account used for the Jira Connector has "Modify Reporter" permissions on the relevant Jira Project. 
• Please see the following article for more information on the required permissions for the API Service Account:  Jira and Jira Align Integration: Creating an API Service Account
