Issue Summary

In Team-managed projects when removing a Field from the issue layout that is used in a Form the Error message displays the Field ID instead of the field name making it difficult to locate the field to revert changes or know what field was removed from the form.

Steps to Reproduce

1. Create or edit a Form
2. add fields to form
3. Navigate to Project settings > Issue types > Select issue type associate to the form you created
4. Remove one of the fields from the form under the issue type layout
5. Navigate back to the Form

Expected Results

Error message Shows Field name that was removed under the "Remove unsupported fields in this form" warning message

Actual Results

The warning shows the Field ID, Noting it is difficult locate field ID's in team managed projects:
 

Workaround:

Copy the field ID and Go to the issue navigator (Filter > View All Issues) and switch to JQL
In the example below the Project was AAAA and the field ID from the error was "customfield_10366". so I would start searching for:

project = AAAA  ORDER BY cf[10366

Autocomplete Will display the Field name "d1" next to the field ID like this:

Navigate back to Project settings > Issue types > Select issue type associate to the form and add the Field back to the Issue layout and save changes to re-associate to the form.
