Installing - TypeError during manage.py migrate

[Akinevz]

Hi,

I'm attempting to run this app on TrueNAS (FreeBSD) 12.0-U8.
I've installed all the recommended dependencies, as well as some that came up as import errors (namely PIL, sqlite, some other ones) and now I am faced with a TypeError.

Below is the dump:

root@ytsm:~ # python3 --version
root@ytsm:~ # su download
$ cd
$ cd ytsm/
$ cd app/
$ python3 manage.py migrate
INFO:root:Initialization complete.
2022-05-30 10:39:36,987 | root | appmain.py:47 | INFO | Initialization complete.
