Can't Get Workflow Scheme for Project while Syncing Statuses

Problem

You're syncing statuses with the Jira Cloud instance and you've got an error that mapping cannot be found. 

javax.script.ScriptException: com.exalate.api.exception.IssueTrackerException: 
Can not get workflow scheme for project `TEST`. Known projects / workflow schemes: `[:]` Please contact Exalate Support. 
Also failed to get it through REST API: Request: GET /rest/projectconfig/1/workflowscheme/TEST 

Cause

If the statuses don't have global transitions Exalate cannot get the status mapping.

Unfortunately, Jira Cloud REST API does not allow getting all statuses from a workflow of an issue.  

Solution

There is an unofficial REST API provided by Jira's project-config plugin you can use to get the required data.

You need to retrieve the workflow scheme in order to configure additional mapping with the workflow scheme details:

• map project key to the workflow scheme ID.
• workflow scheme ID to workflow details(all workflow details and configuration settings).
• workflow name to workflow details(all workflow details and configuration settings).
