For example:
Goodread book with polish metadata (publisher: Bezdroża)
https://www.goodreads.com/book/show/13298052
or (publisher Ętherworld)
https://www.goodreads.com/book/show/37877462
Both books cause the same error "could not convert string to float".
When importing metadata with Goodreads_rating
i selected to import only publisher and only Goodreads_rating enabled.
