Passport strategy called, passed a Payload user - still null on /users/me?

So I'm diving into passport strategies in Payload at the moment, and I decided to start somewhat small with a passport-custom strategy.

The end plan is to create one that verifies the firebase JWTs from my React Native apps.

I've added it as a strategy in the users collection:

 auth: {
    strategies: [
      {
        name: "custom",
        strategy: () => customStrategy(),
      },
    ],
  },

And here's the customStrategy:

export default (): Strategy => {
  const strategy = new Strategy(async (req, done) => {
    // Extracts the JWT
    const token = extractJWT(req);
    if (!token) {
      done(null, false);
      return;
    }

    // Verifies and decodes the JWT
    const verifiedToken = await verifyToken(token);

    // Finds the user
    if (verifiedToken) {
      const userDoc = await payload.find({
        collection: "users",
        where: {
          oauthId: {
            equals: verifiedToken.user_id,
          },
        },
        showHiddenFields: true,
      });

      // The user exists, so it should work
      const user = userDoc.docs[0];
      if (user && userDoc.docs.length > 0) {
        // Yes, user exists. Passing the user document to done
        done(null, user);
        return;
      }
    } else {
      done(null, false);
    }
  });

  return strategy;
};

It's green down until the done() callback.

The user exists and is passed to the callback.

But

still returns null.

The strategy names seems to be (simplified version:)

, when set up in Payload where the passport.use() is called with the strategy.

Ideas? Am I missing anything obvious in the implementation?

Overriding the /users/me endpoint to return req.user solves the issue. The strategy looks like it's been working all along 😅
