I looked up the documentation for the proxyservice module and it says responses are formatted in a specific way:

@Froast

Responses are different with ProxyService: instead of just the body, a table is returned with a dictionary of headers in the headers field, the body in the body field, and the status code and message in the status field.

    "set-cookie": "one=two;",
    "content-encoding": "gzip"
  },
  "body": "Success",
  "status": {
    "code": 200,
    "message": "OK"
  }
}
