Issue Summary

Jira Service Desk projects allow the Priority field to be hidden. The value will be NULL which will trigger a bug when using "Create Linked Issue" so the priority will not be set as per the default from the Priority scheme in the target project.

This is reproducible on Cloud: Yes

Steps to Reproduce

1. Create two Projects, One should be Service Desk type.
2. Make sure the Default Priority is "Low" in the Priority scheme.
3. Go to the Service Desk project and hide the Priority field on the Create issue form.
4. Create a ticket in the Service Desk project using "Create Linked Issue"

Expected Results

The Priority field on the newly created issue should have the default value when Priority is not provided.

Actual Results

The Priority field on the newly created issue will not have the default Priority that is configured in the Priority scheme.

Workaround

Workaround 1:

Show the Priority field on the Create issue form (for "Create Linked Issue") so the users can set it while creating an issue.

Workaround 2:

Use an automation rule to set the Priority after an issue is created.
