Describe the Bug

I have this code in _middleware.ts to check URL validation using graphql.

Whenever I use "next start" it works fine, but whenever I use "next build" I get the error:
Dynamic Code Evaluation (e. g. 'eval', 'new Function') not allowed in Middleware pages/_middleware

Expected Behavior

I want to use graphql requests in middleware. What do I need to change?

To Reproduce

1. Create a project with graphql
2. Create middleware.ts with graphql request and put variables into a request.
3. Run "npm run build" or "next build"
4. Get an error
