Sveltekit + surrealdb-adapter + email magic link login does not work

Clone the reproduction repository and follow README.md to configure the environment, start SurrealDB, and run the SvelteKit development server. Reproduce the magic-link login and inspect the @auth/core/lib/utils/web.js stack entry alongside the adapter session data. Done means the callback completes without the expires error, a login cookie is saved, and the user is logged in.

Describe the issue

When signing in with email, after clicking the sign in link in the email, the following error occurs (with full log of a sign in)

[auth][error] TypeError: option expires is invalid

How to reproduce

• Clone the github repo (https://github.com/Z-snails/authjs-email-error)
• Install the deps (with pnpm install or npm install)
• See README.md for how to configure .env (I used sendgrid as the email server)
• Start the surreal server with surreal start (helpful to use tmux or similar)
• Start the dev server npm dev
• Open in browser
• Click Sign In
• Enter email address
• Click on link in email

Expected behavior

I should be logged in and a login cookie should be saved in my browser. Neither of these occur, instead an error 500 is returned.

Although the user shows as verified in the database.
