Response body null though http debug show the response body

Grafana k6 OSS Support
1

I am using the scenarios option of k6.

export const options = {
  discardResponseBodies: true,
  scenarios: {
    phase1: {
      executor: 'per-vu-iterations',
      vus: 1,
      iterations: 1,
      startTime: '0s',
      maxDuration: '5s',
      exec: 'phase1'
    },
    phase2: {
      executor: 'per-vu-iterations',
      vus: 1,
      iterations: 1,
      startTime: '5s',
      maxDuration: '10s',
      exec: 'phase2'
    },
  },
};

I am doing two different user login in 2 different phases and then making some api call.

export function phase1() {
   const api = new API();

  api.someAPICall();
}

export function phase2() {
   const api = new API();

  api.someAPICall();
}

in API class i have my auth api which return me the token and i can use that.

I enabled the http_debug=full when running k6,

I see the response body in console for http_debug but when i read in my file body is returning null but response code is 200, no issue with response i test it with postman also.

const response = http.post(`${host}/auth`, JSON.stringify({email, password}), {
        headers: {'Content-Type': 'application/json', 'Accept': 'application/json'},
      });
      check(response, {'auth pass': (r) => r.status === 200});
      body = response.body;
      return JSON.parse(body).token;
}

Hi @tailorravat !

Welcome to the community forums! :wave:

I see that you’ve set discardResponseBodies: true (See details Options reference), so that’s probably the reason why bodies are null.

Let me know if that answers,
Cheers!
