Issue Summary

In Jira Cloud, when users attempt to leave a required single-select (single choice) custom field empty on the issue view screen, the following misleading error message is displayed:

We couldn't update the <field name> value.
You can try again in a few minutes, or refresh the page.
Try editing the field again.

This message does not clearly indicate that the field is required, potentially leading to confusion for users.

Steps to Reproduce

1. Create a single-select (single choice) field and add it to your issue view screen
2. Add a value to the field
3. Try updating the field value to empty

Expected Results

This would clearly inform the user that the field cannot be left blank, preventing confusion and avoiding the impression that the error is due to a system or network issue.

Actual Results

We couldn't update the <field name> value.
You can try again in a few minutes, or refresh the page.
Try editing the field again.

Workaround

Currently there is no known workaround for this behavior.
