Hey Guys - I’m following the auth0-authentication template tutorial (https://github.com/graphcool/templates/tree/master/auth/auth0) to try and get auth0 set up in my app and i’m getting this error and I can’t figure it out:

The resolver function authenticate is not nullable, but the function returned null.

Anybody have any ideas on how I could fix this?

From my experience, that usually means the script is crashing somewhere even before the resolver function starts (for example, if the imports are failing). Did you change the resolver file somehow?
