TypeError: Cannot read properties of undefined (reading 'split') cypress_runner.js 198481

Current behavior

I have a test failing in CI that I want to run locally to debug.

I cannot get cypress to run locally—which I’ve always been able to do until recently.

I’ve deleted caches at /user/Library/Caches/Cypress/*, reinstalled countless times, tried on two different machines. I’ve also gotten my coworkers to run locally and they don’t have issues.

Whenever a test is run I get this error. It occurs regardless of the test. I verified this using the getting started test from the docs:

describe('My First Test', () => {
  it('Does not do much!', () => {
    expect(true).to.equal(true)
  })
})

The top of the stack trace leads to this from cypress_runner

var splitStack = function splitStack(stack) {
  var lines = stack.split('\n');
  return _.reduce(lines, function (memo, line) {
    if (memo.messageEnded || stackLineRegex.test(line)) {
      memo.messageEnded = true;
      memo[1].push(line);
    } else {
      memo[0].push(line);
    }

    return memo;
  }, [[], []]);
};

It seems like others have had similar issues. I noticed that popper.js.map is 404ing in the terminal.

Desired behavior

Trying to get any test to run. It’s failing before I can.

Test code to reproduce

Using this test as a sanity check from the docs:

describe('My First Test', () => {
  it('Does not do much!', () => {
    expect(true).to.equal(true)
  })
})

Use cypress open and click it!
