This should be fixed, but it seems to me that you're trying to import an audio book media to a spoken book. That's correct?

Are spoken books and audio books not the same in readarr? I choose spoken book because the only options I see are eBook and Spoken book. I assumed spoken book meant audio book.

Yeah, sorry. My head is in multiple places. That's correct, audiobook to ebook.

Are you saying I should be importing audiobooks (m4b in this case) to ebooks instead of spoken books?

[mynameisbogdan]

I'm saying you should be importing audiobooks to spoken books, because in the error it looks like you're trying to import m4b to an ebook. I'm not familar with calibre, but it only checks for ebooks formats here:

I'm not trying to import to ebooks. See the screenshots below.
