Tests failed on receive a response -The "url" argument must be of type string. Received undefined

[martynaol]

I have :

const { Given, When, Then, Before } = require('@cucumber/cucumber');
const { spec, request } = require('pactum');

Given('I have the layout', async () => {
  await spec()
    .get('/layouts')
    .expectStatus(200)
    .stores('layoutId', 'data[0].id');
});

When('I assign the layout to the ad unit', async () => {
  await spec().post(setLayoutUrl).withBody({
    layoutId: '$S{layoutId}',
  });

When('I receive a response', async () => {
  await spec().toss();
});

Then(
  'I have successfully assign to ad unit, the response should have a status {int}',
  code => {
    spec().response().should.have.status(code);
  }
);
});

Currently I use mix of approaches. So I have :
const pactum = require('pactum');
let spec = pactum.spec()
Sometimes inside the test I use

`await pactum
    .spec()
    .get(`/clients/)
    .withQueryParams({
      level: 'adgroup',
    })
    .expectStatus(200)
    .returns('data[0].id');`

or

spec = pactum.spec();
  await spec.post('/set-layout).withBody({
    layoutId: null,
    pageId: null,
  });

Its works, but I'm curious what is a difference. Especially, I need re-initial spec each time

[ASaiAnudeep]

The method spec will create an instance through which we can make a single request. Please refer this for more usage details.

const spec_one = spec();
const spec_two = spec();

The method toss will execute the spec and returns a promise. Please refer this for more usage details.

await spec().get('/api/users').expectStatus(200).toss();
await spec().get('/api/projects/p1').expectStatus(404).toss();

In your step definitions file, you have created an empty spec and running without defining any request details.

When('I receive a response', async () => {
  await spec().toss();  // empty spec, this will throw an error
});

Thank you very much for your fast reply. Now, things seems clearly
