Issue Summary

When creating a new Epic opening the creation page on a new tab and not specifying the required field 'Epic Name', Jira does not create the Epic and returns with an error that does not specify it's proper name, but it informs 'customfield_10104' instead.

Environment

We've replicated this issue on all versions from Jira 7.0 up to Jira 7.13.

Steps to Reproduce

1. Open the "Create" page on a new tab of the browser
2. Select 'Epic' issue type, and click to create the issue without specifying any information

Expected Results

Returns an error message specifying the field's name like any other field, for example "Epic Name: Epic Name is required".

Actual Results

It returns the error message "customfield_10104: Epic Name is required".

Notes

Any other system or custom field returns with it's proper name before the description of the error.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
