version 1.21.1 infinite loop issue

[jimka...@yahoo.com]

Just trying to update to version 1.21.1 from 2.20.4. the app runs fine under 2.20.4.

Under 1.21.1, the welcome app comes up fine.  The admin/default/site page comes up fine. But when I start the app (http://127.0.0.1:8000/MFMCurrAssetMgr/default/user/login?_next=/MFMCurrAssetMgr/default/index) I hit an infinite loop in yatl/template.py?,  culminating in a RecursionError.

Given the traceback is entirely within gluon code, with no obvious reference to my code other than the URI above, I'm hoping someone can give me pointers to where to look next. I've looked in the default controller and tried tracing  but it never actually seems to get into executing my default/index.

Environment is MacOS 10.15.7. Python is 3.7.8. I'm doing the upgrade with web2py source. 

Here's the start/end of the traceback

Thanks in advance

Jim

Sorry. The web2py version should obviously have been 2.21.1 in my message

[jimka...@yahoo.com]

No input :-( 

Guess we'll need to stick with 2.20.4. Don't really have a lot of time to put into the 2.21 migration, at least for now. :-( :-(

When does it happen?  After you have logged in? Do you get the login page?
