    Are you running this locally? This repo doesn't seem to be actively maintained anymore. I made a fork at https://bookdrop.cc. You may have more success with that, and I'd certainly be happy to help with any issues you incur trying there.

    I did a bit of investigation... The error is in the epub itself, not the services.

    The fatal lines are:

    Error(prcgen):E24010: Hyperlink not resolved in toc: .../part0000_split_000.html#0-5112cb76...
    Error(prcgen):E24001: The table of content could not be built.

    Your epubhas a link that doesn't exist in part0000_split_000.html. This is a known issue with epubs generated by older versions of calibre (yours was built with calibre 3.48.0 from ~2019).

    You may be able to use a newer version of calibre to fix it in the Edit book interface. I believe there's a repair/fix option somewhere there.

    I never touched calibre 😅 But guess the way it was shared with me was using an older calibre.

    But I can repair the books myself, il see
