Undici throws a terminated error

Bug Description

I have a bug with graphl-codegen which is very likely caused by undici closing the connection and sending a terminated signal?

I have double checked my backend with various graphql clients and plain http requests doing the introspection query, the bug is definitely in undici.

The server receives the request, but it is terminated.

A stacktrace is included below:

@thomasaull @LiamKarlMitchell, I got another solution for that, just use node-fetch instead of undici for consuming the api.

schema:
  - http://localhost:8000/graphql:
      customFetch: 'node-fetch'

Reference: https://www.graphql-code-generator.com/docs/config-reference/schema-field#customfetch
