Using firebase adapter + firebase security rules

[DiegoGonzalezCruz]

Hi!
I'm using firebase + nextauth, and I'm having issues authenticating my users in firebase.
At the moment, I'm passing the custom token generated in the jwt callback, to the session callback, and using useEffect in my redirection page to autheticate the user in firebase.

async jwt({ token, user, account, profile, isNewUser }) { if (isNewUser || user) { const additionalClaims = { isStudent: true, isTeacher: false, isStaff: false, isAdmin: false } const customToken = await adminAuth.createCustomToken(token.sub, additionalClaims) console.log(customToken, '***customToken') token.customToken = customToken } return token }, async session({ session, token, user }) { if (session?.user) { session.user.id = token.sub session.customToken = token.customToken } return session },

If I set the rules as 'request.auth !== null', then users can't sign In, as in the process of signing in, the adaptator create documents without being authenticated.

any lights about it? I'm totally losts.
