Answer 1

I have been able to get this to work by using the following code:

 providers: [
    CognitoProvider({
      clientId: process.env.COGNITO_CLIENT_ID,
      clientSecret: process.env.COGNITO_CLIENT_SECRET,
      issuer: process.env.COGNITO_ISSUER,
      checks: ['nonce']
    })
]

This is with:

    "next": "^14.1.4",
    "next-auth": "^4.24.5",

Had a similar problem, checks: ['nonce'] did the trick. – Adamite
