Issue Summary

When attempting to split an issue that contains the required field "Story Points", Jira throws an error that the field must be populated even though the user is already informing an Estimate in the Split issue dialog

Steps to Reproduce

1. Create a Validator in the workflow making the Story Points field required
2. Try to Split the issue by going to Backlog > Right-click on the issue > Split
3. On the Slit issue dialog, set an Estimation for all issues

Expected Results

The issues should be Split with no errors

Actual Results

Update 1 February 2024

The following error now only appears on the Network panel: An error "Error occurred while creating issue through workflow: Field Story Points is required" is displayed.

The UI error is more generic:
 

Couldn't split the issue
We're having some trouble splitting the issue. Refresh the page and try again.

Workaround

In order to work around this error, you can remove any Validators or Post Functions from the Create Issue and then re-run the Split.

After successfully splitting the issue, you can then re-add any Validators or Post Functions to workflows that you removed.

Workaround : 2

Make the field mandatory in the field configuration and remove the field from WF validator. Ref : make-field-required.mp4
