^^Listen to this person.
Back in 2013, after Kasdan was first announced to be writing a spin-off film, he specifically said he wasn't looking at the books.
That said, it doesn't prevent the movie from having similarities to the books. They just wouldn't be planned that way.
And it could also be possible if Lucas developed any background or reference material about Han's past, those ideas could end up in both the books and the movie. But that's just me speculating.
