In NestJS with Fastify, middleware attaches values to req.raw. This is because middleware runs before the request gets wrapped by the FastifyRequest object, so all value attachments are made to the IncomingRequest object (same as Express Request object). Fastify will then wrap the IncomingRequest in its own FastifyRequest object and expose the IncomingRequest through req.raw meaning the user you are looking for is at req.raw.user not req.user. If you want to have the same functionality across Express and Fastify, I'd suggest using a Guard instead.
