Hello,

Have a look at the create transition in the workflow for the Epic issue type. I guess, there is a custom validator. Out of the box you can fill the Epic Link with one symbol and it should work.

I had tried a lot of names, but it still gives me alert asking me to provide a short name, I even tried to put just one number or a letter! What's going wrong here?
