Summary

Unable to clone issues due to "Error occurred while creating issue through workflow" error

Environment

Jira Server or Data Center.

Diagnosis

The following error is found in the logs when the clone action is performed:

/secure/CloneIssueDetails.jspa [c.a.j.bc.issue.DefaultIssueService] Error occurred while creating issue through workflow: 
com.atlassian.jira.exception.CreateException: Error occurred while creating issue through workflow: 
at com.atlassian.jira.issue.managers.DefaultIssueManager.createIssue(DefaultIssueManager.java:519)
...
Caused by: [InvalidInputException: [Error map: [{customfield_XXXXXX=Field Type is required.}]] [Error list: [[]]]
at com.googlecode.jsu.util.ValidatorErrorsBuilder.process(ValidatorErrorsBuilder.java:46)
at com.innovalog.jmwe.plugins.validators.GenericValidator.validate(GenericValidator.java:133)

Cause

It's important to note upfront that cloning an issue will use the "Create" transition for that workflow. Therefore, workflow validators and post functions can prevent issues from being cloned. In this specific case, a workflow validator from the Jira Misc Workflow Extensions (JMWE) is preventing the cloned issue from being created.

Solution

Navigate to the workflow being used by the cloned issue and review the validators and post functions:

1. Select  > Issues.
2. Click Workflows.
3. Find the relevant workflow and click View.
4. Click Edit.
5. Click Diagram to view the workflow diagram.
6. Select the "Create" transition by clicking the grey arrow at the top of your workflow.
7. Click "Validators" once the transition detail box pops up on the right-hand side of the screen.
8. Review all validators and post functions.
