[Bug 1505831] [NEW] Pecan: policy evaluation error can trigger 500 response

 

Public bug reported:

in [1] if policy_method == enforce an PolicyNotAuthorizedException is triggered.
However, the exception translation hook is not called, most likely because the on_error hook is not installed on other policy hooks.
This might be logical and should therefore not be considered a pecan bug.

The policy hook should take this into account and handle the exception.
