调研方向
The crash is from putting GraphQL variables JSON (including emoji) into the _dd-custom-header-graph-ql-variables header that expo/fetch rejects on Android. Start in packages/react-native-apollo-client where variable tracking is configured and those custom headers are attached. Encode, strip, or skip non-ASCII header values for this path, then re-run an Apollo mutation with emoji in variables on Expo 57 Android.

描述
Describe the bug
After upgrading Expo to 57 we noticed this Android error ApolloError: fetch failed: Call to function 'NativeRequest.start' has been rejected. when performing GraphQL mutations with variables that contain emoji's. I believe this happens because the default fetch package changed from RN fetch to expo/fetch in Expo version 56. expo/fetch uses different native request classes which only accepts ASCII chars in headers of requests on Android. It seems like that @datadog/mobile-react-native-apollo-client does not properly set or unset these headers for this type of request.
Reproduction steps
- Use Expo 57
- Use
@datadog/mobile-react-native-apollo-clientin Apollo client - Ensure variables are tracked
- Perform Apollo Client mutation on Android with emoji's inside variables
SDK logs
ApolloError: fetch failed: Call to function 'NativeRequest.start' has been rejected.

Expected behavior
Apollo client requests should not fail because of dd graphql variable tracking.
