Cannot build with middleware and target: serverless

[revmischa]

I don't know if this is a serverless-next issue but this warning has become an error for me in the latest nextjs

> Build error occurred
MiddlewareInServerlessTargetError: Next.js Middleware is not supported in the deprecated serverless target.
Please remove `target: "serverless" from your next.config.js to use Middleware.

And my next.config.mjs is empty

I'm working on a new setup that will solve this: https://github.com/jetbridge/cdk-nextjs
