Description

when using the Upload extension, normal requests without upload are executed with an error

in the demo i use the server https://countries.trevorblades.com/graphql
i also checked on the server of my project, requests are also not executed there, but a slightly different error

is this a bug on the extension side or on the server side?

Interesting! I'll investigate on my side over the next few days.

'content-type': ``,

i noticed that without the extension server sends
content-type: application/graphql-response+json; charset=utf-8

but with the extension server sends
content-type: application/json

i understand why you are sending an empty content-type, but it looks like it is being sent empty on every request

is it possible to send an empty content-type only if the request contains upload?

Yes, and that is what it should be already doing :)

If you want to take a crack at a PR and test, feel free! If the issue is just the extension code, should be accessible for others to help here.
