Unable to download Mangas from MangaDex

[Ponkhy]

Describe the bug

Hello,

I just installed kaizoku on my server, unfortunately I'm encountering the issue of being unable to download Mangas. When I add a new one to the library it downloads 1-4 chapters and then stops. After looking more into it I can see this error in the logs:

kaizoku  | X /config/.config/mangal/sources/MangaDex.lua:130: attempt to index a non-table object(nil) with key 'body'
kaizoku  | stack traceback:
kaizoku  |      /config/.config/mangal/sources/MangaDex.lua:130: in main chunk
kaizoku  |      [G]: ?

I've also noticed that I'm now unable to open the website beceuase of the error ERR_HTTP2_PROTOCOL_ERROR. Maybe they've implemented some kind of protection in order to avoid mass downloads? Because after a few hours it's possible to access the website again. Would it be possible to build in a custom delay in order to avoid the issue, or could it be something else?

Many thanks!

Yes, they have rate limits. See https://api.mangadex.org/docs/rate-limits/#rate-limits

To add a custom delay, I need to rework the queue system.

Ahh, I see, thank you! Yea a custom delay would be pretty good, otherwise MangaDex at least is not usable at the moment. Thanks for the quick reply!

@Ponkhy You can retry them, that's what I did when I added a bunch of new manga. Doing this once a day or so for a week had everything catch up

Click into the fail queue

Click failed, and then retry all

Yeah not sure whats with the rate limit, Tried out tachidesk and used mangadex extension downloads chapters without a issue, could it be if you attempt to download multiple chapters at one time it puts a limit on you? Its a shame mangadex cant really be used for the time being....

Also Clean all results to Internal Server Error

Yeah I ran into issues with mangadex too, my biggest issue is that mangadex will ban me at the network layer temporarily, so I can't even browse mangadex anymore until the temporary ban lifts (usually not more than an hour or two)

A real shame, mangadex used to be my favorite source, although it has one weakness, often it releases several group releases of the same chapter so you get "dupe" content.
