Prevent “Unhandled promise rejection” error

Question

In my server app I want to return a \"forbidden\" value when the user has no permissions for the endpoint.

I would give advice which deviates from the accepted answer. I wouldn't recommend using the return statement to provide an Error - this is ignoring the exact intention of throw!

I offer that your intuition and the accepted answer are over-engineered. Simply do this instead:

if (!isCollab) throw new Error('FORBIDDEN');

If you don't want a stack trace forget about all the overhead and simply do:

if (!isCollab) throw 'FORBIDDEN';
