nodejs tests randomly fail on CircleCI

We are building an application using nodejs and writing asynchronous tests for it using Jest. There is a problem we have been facing for a while now in regards to tests; sometimes tests fail on CircleCI while other times they pass. And yes, we are using async/await method to wait for the data to be fetched first before doing an assertion. Here is a snippet from the tests file:

it('should return the expected number of trips', async () => {
  const postResp = await request(app)
    .post('/api/v1/requests')
    .set('authorization', token)
    .send(mockRequest);
  const createdRequestId = postResp.body.request.id;

  const getResp = await request(app)
    .get(`/api/v1/requests/${createdRequestId}`)
    .set('authorization', token);
  expect(getResp.body.requestData.trips).toHaveLength(2);
});

And this is the error that was thrown by CircleCI in regards to this block of test: TypeError: Cannot read property 'trips' of undefined
