Debugging

With DEBUG=1 flag, you can see a verbose output in your logs to debug all the HTTP requests and responses from the client to the subgraphs.


[2024-08-28T12:06:25.861Z] DEBUG upstream - 887a7efc-7324-4612-b1a7-0b76ada9fd7a - fetch request {
  url: 'http://localhost:44725/graphql',
  method: 'POST',
  body: '{\n  "query": "query MyTest{foo}"\n}',

    'content-type': 'application/json',
    'x-request-id': '887a7efc-7324-4612-b1a7-0b76ada9fd7a'
  },

}

Also in this mode, the gateway will add details about the underlying HTTP requests and received responses in case of an error;
