Failed to map roles to user in Test Mode

Content

Hi everyone

I am experiencing a problem with trying to activate my process in test mode, I get an error saying that it failed to map roles to the current user.

However, when I publish the application, activate it and then add roles manually to the user, it does work. I have tried adding them one by one but it showed me no errors, only when I do this in test mode. 

What can I do to help this?
