Next-Auth with FaunaDB Dev Get Session Error - next.js

Question

I've set up Next-Auth on my NextJS project to use FaunaDB. I've managed to get it working on my production environment, however, it seems to not be working on my development environment, which is using the Fauna Dev docker container rather than the cloud-based database.
Whenever I run the dev server, I get the following error log;
https://next-auth.js.org/errors#fauna__get_session_error [NotFound: instance not found] {
description: 'Set not found.',
requestResult: RequestResult {
method: 'POST',
path: '',
query: null,
requestRaw: '{"get":{"match":{"index":"session_by_token"},"terms":"86b962d600c3f53d41d5140de6daed654a473e670a99943d7fb301a4fc86357e"}}',
requestContent: Expr { raw: [Object] },

responseContent: { errors: [Array] },

},
startTime: 1630008521471,
endTime: 1630008522280
}
}
I've followed the guide to set this up and continue to get the same error. I've removed and recreated the fauna docker container several times, still the same error. I also have some data that I can access in the local Fauna Dev database, so that seems to be set up fine. Also if I change my .env.local environment variables to the ones I use on production, it all works fine, but of course is then using the cloud database.
Here's a comparison of my production and local variables, with private keys removed;
# .env.local
GOOGLE_ID=<removed>
GOOGLE_SECRET=<removed>
NEXT_PUBLIC_FAUNA_ADMIN_KEY=<removed>
NEXT_PUBLIC_FAUNA_DOMAIN=localhost
NEXT_PUBLIC_FAUNA_GRAPHQL_ENDPOINT=http://localhost:8084/graphql
NEXT_PUBLIC_FAUNA_PORT=8443
NEXT_PUBLIC_FAUNA_SCHEME=http
NEXTAUTH_URL=http://localhost:3000
# production env
GOOGLE_ID=<removed, identical to local>
GOOGLE_SECRET=<removed, identical to local>
NEXT_PUBLIC_FAUNA_ADMIN_KEY=<removed, different to local>
NEXT_PUBLIC_FAUNA_DOMAIN=db.eu.fauna.com
NEXT_PUBLIC_FAUNA_GRAPHQL_ENDPOINT=https://graphql.eu.fauna.com/graphql
NEXT_PUBLIC_FAUNA_SCHEME=https
NEXTAUTH_URL=https://dnd-compendium-five.vercel.app
And for good measure, here's my [...nextauth].ts file;
import NextAuth from "next-auth";
import Providers from "next-auth/providers";
import * as Fauna from "faunadb";
import { FaunaAdapter } from "#next-auth/fauna-adapter";
const isProduction = process.env.NODE_ENV === "production";
const client = new Fauna.Client({
secret: process.env.NEXT_PUBLIC_FAUNA_ADMIN_KEY,
scheme: process.env.NEXT_PUBLIC_FAUNA_SCHEME === "https" ? "https" : "http",
domain: process.env.NEXT_PUBLIC_FAUNA_DOMAIN,
...(isProduction ? {} : { port: +process.env.NEXT_PUBLIC_FAUNA_PORT }),
});
export default NextAuth({
// Configure one or more authentication providers
providers: [
Providers.Google({
clientId: process.env.GOOGLE_ID,
clientSecret: process.env.GOOGLE_SECRET,
}),
// ...add more providers here
],
adapter: FaunaAdapter({ faunaClient: client }),
});

Here's several documents from the production Fauna database, with personal info removed;

Which verisons of next-auth and the adapter are you using? They recently released a v4 beta and matching adapter beta's. Maybe you'll have more luck with those newer releases 👍
