If you see the "E-mail address of PersonIdent must not be null" error message when you create or update a merge request, it may mean that you haven't specified your email address in your profile. Access your profile, verify your user email address, then retry the merge request.

For information about how to provide and verify your email address, see Update Your Email Address. You'll also need to ensure that you've subscribed to merge request notifications. For details on how to do this, see Configure Your Global Email Notifications.
