RangeError: Maximum call stack size exceeded when making cy.request which times out

Current behavior

When making cy.request(url) to the endpoint which does not respond in 30 seconds (default response timeout), cypress crashes with RangeError: Maximum call stack size exceeded error in socket.io-parser, used by bluebird library.

Desired behavior

cy.request(url) should fail the test instead of crashing the cypress.

Test code to reproduce

spec.js:

/// <reference types="cypress" />

context('Network Requests', () => {
  it('cy.request() - make an XHR request', () => {
    // https://on.cypress.io/request
    cy.request('http://localhost:8080').then(r => {
      cy.wrap(r.body).should('contain', 'Hello');
    })
  })
})

server.js:

const express = require('express');
const app = express();

app.get('/', async (req, res) => {
  await sleep(50000);
  res.send('Hello from App Engine!');
});

// Listen to the App Engine-specified port, or 8080 otherwise
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
  console.log(`Server listening on port ${PORT}...`);
});

function sleep(ms) {
    return new Promise((resolve) => {
      setTimeout(resolve, ms);
    });
  } 

Versions

Definitely 6.6.0 and 6.8.0, possibly earlier.

Duplicate of https://github.com/cypress-io/cypress/issues/15101 which we have a reproducible example for now.

@t00 I could also get yours to reproduce after a few tries of stop/starting.

Closing as Duplicate to track in one issue.

@DVGY Looks like @bahmutov is from the cypress team and hopefully might be able to help 😄
