TypeError: option expires is invalid

Question 💬

I am deploying a Nextjs app using Next-Auth to AWS App Runner. I am using the Cognito Provider.

In the logs I can see the following error:

2023-06-29T23:08:26.275-04:00	TypeError: option expires is invalid
	2023-06-29T23:08:26.275-04:00	at serialize (/app/node_modules/cookie/index.js:161:13)
	2023-06-29T23:08:26.275-04:00	at setCookie (/app/node_modules/next-auth/next/utils.js:26:46)
	2023-06-29T23:08:26.275-04:00	at /app/node_modules/next-auth/next/index.js:36:147

I have tried everything to get rid of this. This issue does not occur on localhost.

How to reproduce ☕️

This is my [...nextauth].ts file

export function getOptions(req: NextApiRequest): NextAuthOptions {
  return {
    // @ts-ignore
    adapter: MongoDBAdapter(clientPromise as any),
    secret: process.env.NEXTAUTH_SECRET_KEY,
    providers: [
      CognitoProvider({
        name: 'Cognito',
        clientId: process.env.COGNITO_CLIENT_ID!,
        clientSecret: process.env.COGNITO_CLIENT_SECRET!,
        issuer: `https://cognito-idp.${process.env.COGNITO_REGION}.amazonaws.com/${process.env.COGNITO_POOL_ID}`
      })
    ],
    session: {
      strategy: 'jwt',
      maxAge: Number(process.env.JWT_TIMEOUT!)
    },
    jwt: {
      secret: process.env.JWT_SECRET
    },
    pages: {
      signIn: '/login',
      newUser: '/register',
      verifyRequest: '/verify-request'
    }
  };
}

var nextAuth = (req: NextApiRequest, res: NextApiResponse) => NextAuth(req, res, getOptions(req));
export default nextAuth;

Removing maxAge: Number(process.env.JWT_TIMEOUT!) fixed the issue for now.

how could this be an issue... smh

[fedefrei]

I found out a workaround hardcoding the maxAge number doing this:

session: {
	maxAge: 3600,
},

instead of

session: {
	maxAge: Number(process.env.NEXTAUTH_SESSION_AGE),
},

if its of any help.

Okay, I just did some checking and logging. Turns out that's something wrong in the .env.
In my case, I put a comment message after the number. And it loads everything.

NEXTAUTH_JWT_TIMEOUT=86400 # for 1 day - 86400 = 1* 24 * 60 * 60

process.env.NEXTAUTH_JWT_TIMEOUT // "86400 # for 1 day - 86400 = 1* 24 * 60 * 60"

So, I just need to put the comment above the declaration.

# for 1 day - 86400 = 1* 24 * 60 * 60
NEXTAUTH_JWT_TIMEOUT=86400

It's also a possibility that your postgresql database uses DATE for expiry instead of TIMESTAMP. This is what triggered the error for me.
