I think you need to overwrite headers. So you can add your own headers using operationHeaders mesh config. And add content-type with */*.

How can I debug if the operation is using the correct request headers. Added the operationHeaders but still same error.

You can compare the request coming from Mesh and working another one you send.

I have the same issue, my external server returns application/vnd.api+json; charset=utf-8 instead of application/json. I've tried to add operationHeaders, no luck.

have a content-type 'application/json' but

Same error with stackexchange api(openapi 2.0)
query:

{
  getQuestions(site:"stackoverflow")
}

response:

{
  "errors": [
    {
      "message": "Unexpected error value: \"Operation GET /questions should have a content-type '*/*' but has 'application/json; charset=utf-8' instead\"",
      "locations": [],
      "path": [
        "getQuestions"
      ]
    }
  ],
  "data": {
    "getQuestions": null
  }
}
