RecursionError: maximum recursion depth exceeded while calling a Python object

[Klysas]

I'm using FanFicFare v3.26.0 and tried to download "Release that Witch" from WuxiaWorld.site and WuxiaWorld.co and receive following error. I'm guessing this is because this novel has 1498 chapters.

Large numbers of chapter don't cause recursion errors in HTML processing--that's usually bad HTML in the story or on the site.

I suspect that you removed the debug output before the exception that would have helped tell me what chapter the error was in. If you still have it, that would be nice to see.

I was able to download this without seeing that error, but I did get a different error (connection failure) temporarily on one chapter. Because I had continue_on_chapter_error:true in personal.ini, the download still finished, but I had to remove the bad chapter and do an update.

With huge long stories continue_on_chapter_error:true can be a good idea to not waste all that time just because the network burps.

If you are on window 32bit version of Calibre, I suggest you switch to 64bit.

Assuming resolved.
