Get an "Error: Parse Error: Expected HTTP/" with cy.request on 204 status

[pitivie]

Current behavior

I'm trying to delete item with:

  cy.request({
    method: 'DELETE',
    url: `http://localhost:8000/api/items/${itemId}`,
    followRedirect: false,
    auth: {
      'bearer': 'long token'
    },
  }).then(
    (response) => {
      expect(response.status).to.eq(204);
    }
  )

My server returns a response with 204 status and an empty body (as defined here https://developer.mozilla.org/fr/docs/Web/HTTP/Status/204).
But I get an error from cypress:

When I change server return with a non-empty body (like "foo"), the test passed.

Desired behavior

Cypress should accept empty response on 204

Test code to reproduce

  cy.request({
    method: 'DELETE',
    url: `http://localhost:8000/api/items/${itemId}`,
    followRedirect: false,
    auth: {
      'bearer': 'long token'
    },
  }).then(
    (response) => {
      expect(response.status).to.eq(204);
    }
  )
