Setting required field blocks email requests

[Martyn Bell]

Im using Jira company managed service desk.

Im trying to set up a required field in some of my screens however, every time i set a Custom field as required, the emails been sent to the service desk fail.

I have checked the issue types and configured screens for reference to this field but i cannot see it anywhere.

Has anyone experienced this? or know how to solve?

You have to make the field optional. 

The email handler can't know what to fill in to a mandatory field.
