ValueError: IV must be 16 bytes long

[BlackPreacher]

If I try to save a note for one day, I always get an error-message "There was an error saving. Please try again". In the docker logs I see the python error "ValueError: IV must be 16 bytes long".

I appears if I build the container myself from the cloned github repo, or if I pull the "offical" dockerimage from docker hub. Does anyone other gets these errors?

One complete logoutput is:

See #17

That should fix your issue. Also ensure your key is a multiple of 16
