when i run cum update it starts updating all the manga but then it crashes with the following json error:

it produces a similar error when I try adding a new series from mangadex

running cum version 0.9.1 "Morino Kirin-chan" from pip

I tried adding a manga from one of the other sources (Doki Reader) and it added fine, so it might be an issue with mangadex itself

Might be some of the DDoS mitigation they're currently doing

I think this should fix it: https://github.com/Hamuko/cum/pull/68

@mxnemu thanks that seems to have done the trick! I checked and I was able to update, add new series, and download my manga. Hopefully that fix gets merged to master
