Use in Next.js's middleware.ts causes error

[SkelatorIndy]

Description

When using the openapi-fetch client in Next.js 14.2.4's middleware.ts file, it causes the app to error

Client Error

Server Error

Reproduction

This can be reproduced by using the openapi-fetch client in the middleware.ts file of Next.js. The error does not occur if you use the standalone fetch client

Causes Error:

// Located in another file
const api = createClient<paths>({
  baseUrl: 'https://localhost:5000',
});

export default async function middleware(request: NextRequest) {
  await api.GET('/api/v1/auth/security');

  return Response.redirect(new URL('/', request.url));
}

Works:

export default async function middleware(request: NextRequest) {
  await fetch('http://localhost:5000/api/v1/auth/security');

  return Response.redirect(new URL('/', request.url));
}

I made a sandbox using the latest version of Next.js showing this error occurring with a very minimal setup:
Sandbox Reproduction

Expected result

Should be able to use openapi-fetch in middleware.ts

I believe this is a duplicate of #1569 ?

[SkelatorIndy]

The solution of manually replacing the fetch for the request with the standalone fetch does work, and because of the small scope of where this error occurs it is not a bad solution. However, since that issue mentioned a fix being merged in, and the follow up mentions specifically that the GET requests are fine, which mine is not, I was unsure if this may be a separate but related issue. However, if you do believe it is a duplicate of the same issue mentioned there, then this issue can be closed as a duplicate.

I'm going to take a look at the issue, I'm supposed to have made a PR trying to resolve this but it doesn't seem to cover some cases.
