Upgrade from 3.5.8 to 3.7.4 Issues

[Wyvern77]

I attempted to upgrade from 3.5.8 to 3.7.4 (direct upgrade) and I am now unable to access the "Devices" section. I can see Devices via API, or I can do a global search and find devices that way, but the actual list of all devices in NetBox comes back with the following error:

Has anyone else run into this? Have any ideas on how to resolve? I attempted to roll back, but this is a lab and I did not back things up prior to the upgrade. I do need to upgrade our production version though and need to make sure this does not occur there.

Please get a full backtrace, either by setting DEBUG=True in configuration.py (in which case it'll be displayed in the web page), or setting EMAIL and ADMINS in configuration.py (in which case it will be E-mailed to you)

[markkuleinio]

What he said, plus, what's the reason for you saying that you are upgrading direct from 3.5.8 to 3.7.4 but the error message shows that you are actually running NetBox 3.7.1?

return self.customfield.get_choice_label(value)

Looks to me to be something to do with custom fields. And it also suggests something to do with choice sets which were introduced in v3.6.

Did you run ./upgrade.sh and did it complete successfully? I wonder if you're trying to run v3.7 with an incompletely-migrated database.

Found the issue with the debug. Thank you for pointing me that way!

Ended up being a Custom Field issue of some sort.
