Getting 500 error on Web UI of Sabnzbd

[engkazim2000]

Hello,

We are using Sabnzbd form last few months its working perfectly fine but today its giving me 500 error on webUI can you please guide me how to fix that issue

[safihre]

Well, what is the error? It should show you more than just 500.

I restarted today to get a 500, this was after a patch and reboot.
pip3 install -r requirements.txt shows all satisfied.

NameMapper.NotFound: cannot find 'apikey'

Code: Select all

You need to restart your SABnzbd, it has updated the template files but the SABnzbd itself isnt updated yet,

Weird, it does work now, but the first thing i tried was a restart.
Thanks for fixing my stupid

[safihre]

Great!
Let us know if you experience any bugs or weird behavior on the Python 3 version. It's still a testing-release!

If I can add a "me too!" ...

I've been seeing the same thing while testing installation of the new SABnzbd package on QNAP NAS. Sometimes, I'll get a 500 error - which can be fixed by restarting SABnzbd. But sometimes it starts OK.

This only happens when starting SABnzbd for Python 3 for the first time.

Subsequent startups always seem to be OK.

I just did some changes this week that can cause this. It depends on the cached template-files or the program not beeing restarted truely.

It depends on the cached template-files or the program not beeing restarted truely.

I'm not sure what to make of that.

Is there anything I can do to ensure SAB3 will start correctly first time?

[safihre]

Not sure.. on Windows I never experience these problems, a simple restart of SABnzbd after applying changes is enough.
But you are sure this isn't always working for you?

[safihre]

Maybe it's some caching that the Cheetah-template system does.. Not sure about that or if we can even control it :/

Maybe SABnzbd needs an external restart to get it to really clear its cache, not just the internal restart.

thank you all for the replies.

Today I turned on the machine and then ran sabnzbd+ again and things have changed. Still got an error but its waay different with a trace back:

I have absolutely no idea what I am looking at but it all seems connected to python3 & 3.8

This is a different problem:

It is a bug in Python which is fixed in the latest Python 3.8 and 3.9
