Kobo Sync token contents do not follow the expected json schema #3017

Closed wietsedv closed 6 months ago

wietsedv commented 6 months ago

Describe the bug/problem

Since a couple of weeks synchronisation with Kobo does not work anymore and if I keep wifi on on my Kobo, the battery drains in a day. It appears that the Kobo Sync Token that Kobo gives in request headers cannot be parsed by Calibre Web. Calibre-Web nor Kobo have been updated since it last worked, so I am assuming that this will be hard to reproduce.

Has anyone experienced a similar issue before?

I have tried:

Of course I managed to identify the problem just minutes after posting this issue. I do not have a definitive solution, but my issue is caused by the calibre-web distribution of nixos-unstable. When I switch to the nixos-2311 package, the problem is solved. I will look into fixing the nixos-unstable version later, but since both are calibre-web 0.6.21, it is not a real calibre-web issue. Might be something about python or other package version compatibility.
