Content-type Response Header.

[THILAK6]

The default 'content-type' header that we receive while doing a query is 'text/html', but we expect it to be 'application/json'.
So We tried creating a plugin to set the header and used it in the server. But still unable to get the 'content-type' header or any header that is set in the response.

Hello,

I am encountering the same issue. My Apollo subgraph with Google Cloud Functions is stuck on this issue. Despite attempting to force a JSON response, it still returns an incorrect Content-Type: text/html. This makes it impossible to use Apollo Subgraph with Cloud Functions as expected.

{
  "data": null,
  "errors": [
    {
      "message": "HTTP fetch failed from 'feed': subgraph response contains unsupported content-type: text/html; charset=utf-8; expected content-type: application/json or content-type: application/graphql-response+json",
      "path": [],
      "extensions": {
        "code": "SUBREQUEST_HTTP_ERROR",
        "service": "feed",
        "reason": "subgraph response contains unsupported content-type: text/html; charset=utf-8; expected content-type: application/json or content-type: application/graphql-response+json",
        "http": {
          "status": 200
        }
      }
    }
  ]
}

I am wondering if there is any solution to this problem or if someone is actively working on fixing it? I would greatly appreciate any guidance or updates.
