Error while serving deeplink

I've disabled "allow guest" on a deeplink. This takes me to the login.html page where I enter my username and password. After clicking submit I get a 500 error, and the console in the Modeller says:   I've checked the permissions on the Domain and the User role has full read and write access to the PendingLink object. I suspect this is one of those errors that's masking another error; does anyone with experience of this have any ideas?

Did you give the user also the user role in the deeplink module? That might be the cause of this error. (Security / tab user roles / Edit and then check if the user has the role user in the deeplink module)
