hello friends, i created a nextjs app and im using next-auth with auth0 provider, im getting id_token in the session and i want to verify it in an external backend using the same secret, next-auth use a RS256 algorithm , and i need to pass the secret in an enviromental variable, i use nextjs config to read the file.key and set as NEXTAUTH_SECRET

then in the backend im using the same file.key to verify the token and im getting invalid signature

any posible solution? thanks in advance
