Hello, got a problem using NextAuth :
I've setup everything and had 0 problems by running run dev, now, when i'm trying to deploy it i'm getting errors about URL.. (first of all it's weird because i've setup it.. but anyways)
I've figured out the session is ALWAYS null even if the signIn got sucess..

I couldnt really post a reproductible example, i can tell you i'm using a CredentialsProvider and the way i'm getting the session can be found here :

export async function getServerSideProps(context) {
  const session = await getSession(context)
  // session === NULL
  // there's a fetch here, that creates the error [CLIENT_FETCH_ERROR]
}

Anyone ever figured out a similar problem ?
And then, someone ever fix the problem ?
