Sign up with next-auth sign in function problem

I am working on a school project with next auth. I work on the back end part but I am stuck in the sign up part. When I use the sign in function I am not getting any request for the authorize function from the credentials provider but not getting errors either, because the response seems to be okay. When I look into the google inspector, i'm the network section, I get a warning saying that the header set-cookie starts with Host and Secure.

I really hope someone can help me because I need this to pass my subject and I am getting desperate. Thank you!!!

I´ll adjust my files and codes in photos because of the length this message allows.
