Hi, starting with an app that’s been running for several months running 
web2py 2.17.1 and Python 2.7.14 on maOS 10.14.3 (Mojave), I’m embarked on 
an app migration to Python 3 using web2py 2.17.2 and Python 3.7.2.


This isn’t the first app I’ve converted to Python 3 and and I’ve got a 
pretty good sense for what conversion issues look like - and this problem 
seems different 


I’m stuck and any help would be very appreciated. Thanks in advance


————————————

When I try to run to run the migrated app, problems arise almost immediately


1. Starting web2py up using Python 3 seems to work fine. The welcome and 
example apps seem to run fine

2 I can log in as admin

3. The list of apps is displayed as normal, including my migrated one


4. Selecting my app, I expect to need to login, but without any further 
action, the browser screen says “Invalid function (default/user)” and 
that’s the end of the story.

* Note:* default/user code is unaltered from the we2py distribution

* Note:* default/index is marked “@auth.requires_login()“ and is never 
reached

* Note*: Remove the “requires_login”, index is reached and appears to run, 
but then the app then  hangs presumably because the next step wants the 
user login



Below is the start of the log:
