[7.2.0]Bug: cy.intercept POST terminates cypress process

[lianzhao]

Current behavior

Cypress crashes when I use cy.intercept to intercept a POST request with body

{"SearchType":2,"Keywords":"冀B9QG30","RealNamed":0,"Images":[],"Tags":[],"TopX":100,"Limit":100,"Offset":0}

Desired behavior

Cypress wont crash.

Test code to reproduce

I think it's the same issue with https://github.com/cypress-io/cypress/issues/15901 ?

Versions

• Cypress 7.2.0
• Mac OS 10.14.4

Hey @lianzhao, we have a fix going out in our next release on Monday for the ERR_INVALID_ARG_TYPE error here: https://github.com/cypress-io/cypress/issues/16223 You can download the pre-release version of Cypress to get this fix. Follow the instructions here

I can't determine if your issue is already fixed by this as there's no enough info provided to reproduce it.

Can you try the fix above and verify/close the issue if fixed? Otherwise can you provide a full reproducible example? I tried to recreate the issue with the body provided, but Cypress does not error in my example below.

Thanks!

it('test cy.intercept()', () => {
  cy.intercept('/users').as('postUrl')
  cy.visit('https://example.com')
  cy.window().then((win) => {
    const xhr = new win.XMLHttpRequest()
    xhr.open('POST', '/users')
    xhr.send({ 
      "SearchType": 2, 
      "Keywords": "冀B9QG30", 
      "RealNamed": 0, 
      "Images": [], 
      "Tags": [], 
      "TopX": 100, 
      "Limit": 100, 
      "Offset": 0 
    })
  })
  cy.wait('@postUrl')
})

@jennifer-shehane Sorry for the late reply, here's my code to reproduce:

it('test cy.intercept()', () => {
  cy.intercept('POST', '/users').as('postUrl');
  cy.visit('https://example.com');
  cy.window().then(win => {
    fetch('/users', {
      headers: {
        accept: 'application/json',
        'accept-language': 'en-US,en;q=0.9,ja;q=0.8',
        authorization:
          'Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MjEwNjkyNDgsImlkIjoiOWIyNmIwMTctZjFkNy00Mjk4LWFmMjYtODRhOTI0NjY2NGYyIiwib3JpZ19pYXQiOjE2MjAzNTEwODZ9.YKjKVpA_Y8fvTwrmhTh5EwjuW5eITM4e2r7ZXWtdrZQ',
        'content-type': 'application/json',
        pragma: 'no-cache',
      },
      referrer: 'http://192.168.2.159/',
      referrerPolicy: 'strict-origin-when-cross-origin',
      body:
        '{"SearchType":2,"Keywords":"冀B9QG30","RealNamed":0,"Images":[],"Tags":[],"TopX":100,"Limit":100,"Offset":0}',
      method: 'POST',
      mode: 'cors',
      credentials: 'include',
    });
  });
  cy.wait('@postUrl');
});

And here's my cypress config

BTW, cypress won't crash if you remove the Chinese character 冀 from the code above.

Thank you for your help!
