要約:
When user is editing the transition name, the error "common.forms.ajax.servererror" is thrown in the UI. Here is the screenshot for more information.
Environment :
8.13
Diagnosis:
When checking the har file, check the PUT endpoint that tries to make the modification of transition name:
rest/workflowDesigner/latest/workflows/transitions- You should see that it always picks up sourceStepId as 1 and system checks for step with that particular ID in system for that workflow:

When checking the Jira logs, you should see the java.lang.NullPointerException as mentioned below:
Uncaught exception thrown by REST service: null java.lang.NullPointerException at com.atlassian.jira.workflow.edit.Workflow.isDuplicateStepTransitionName(Workflow.java:793) at com.atlassian.jira.workflow.edit.Workflow.isDuplicateTransitionName(Workflow.java:743) at com.atlassian.jira.workflow.edit.Workflow.isDuplicateTransitionName(Workflow.java:506) at com.atlassian.jira.workflow.edit.WorkflowTransitionsImpl.verifyTransitionCanBeUpdated(WorkflowTransitionsImpl.java:325) at com.atlassian.jira.workflow.edit.WorkflowTransitionsImpl.updateTransition(WorkflowTransitionsImpl.java:95) ... 3 filtered
原因:
As the step with ID 1 is not found in the system, it fails with NullPointerException.
ソリューション
- Export the workflow as xml.
- Open it is up in text editor.
Check for tag <initial-actions> in the XML.
Notice what step ID is mentioned in
<unconditional-result old-status="null" status="open" step="10">- When status is open(which is create step), API checks for step ID 1 as next step.
- Take the back up of XML. Modify this step ID to 1 and also track corresponding <step> tag to modify its ID as well to step id="1"
- Delete the existing workflow and import the modified one.
Here is an example of edit workflow for reference:
