Issue Summary

Split issue fails if there is a field required validator in the issue transition

Steps to Reproduce

1. Add a field required validator to the creation step of a workflow.
2. Create an issue that employs the workflow from step 1.
3. In a software board, go to the backlog locate the issue, and attempt to split it (right click > Split issue)
4. Fill the details of the new issue(s) to be created and press Split.

Expected Results

The issue is split as expected and new issues are created.

Actual Results

An generic error is displayed. "Couldn't split the issue. We're having some trouble splitting the issue. Refresh the page and try again."

Note: it is not clear if the validator is working as expected and the error is just not showing the actual message (the validator message) or if the Split issue action should ignore the field required validator, like it does for the field configuration (as having the field as required in the field configuration does not prevent splitting the issue).

Workaround

Ensure there are no validators in the issue creation screen. Instead, you could use the field configuration to set the field as required, or set a validator for that field on any successive transitions other than the issue creation one.
