cy.wait on an array return TypeError Cannot read property 'split' of undefined line 136007:55

[mykodimy]

Current behavior

Cypress version 13.4.0

cy.wait on an array return "TypeError: Cannot read property 'split' of undefined"
/__cypress/runner/cypress_runner.js:136007:55

Here is the example code:

cy.intercept('**/Submit').as('submit');
cy.intercept('**/GetDetails').as('getDetails');
cy.get('#saveBtn').click();
cy.wait(['@submit', '@getDetails']);

@mykodimy Could you provide an example we can run? There's likely something specific about your code or app that is necessary to see this error, since we have tests around waiting for standard requests in an array.

[mykodimy]

I didn't have example as my app is an internal website. The same e2e code functions properly when I downgrade from Cypress 13.4.0 to Cypress 12.17.3. This issue only happen after I upgrade to Cypress 13.

Will the stack trace help?

I am also running into the same issue
#28219

tried with 13.5.0 this morning and same errors 😢

https://cloud.cypress.io/projects/oy3esu/runs/8864/overview?roarHideRunsWithDiffGroupsAndTags=1

After upgrading from 13.2.0 to 13.6.2, we see the same issue:

• The issue does not occur in 13.3.0, but is reproducible from 13.3.1 onwards.
• In our tests, we wait for multiple requests to finish and therefore use a wait on an array.
• The bug is triggered only in one test; I don't see an obvious difference between this test and the other tests.
• The bug occurs every time I run that test; meaning it is reproducible.
• Unfortunately, I cannot share code.

Hope you guys can identify the source of the bug since this prevents us from upgrading to the current version. Let me know in case I can be of assistance.

I would suspect that this issue was added with #27806 as part of 13.1.1. Specifically this:

// sort responses based on browser request ID
const requestIdSuffixA = a.browserRequestId.split('.').length > 1 ? a.browserRequestId.split('.')[1] : a.browserRequestId
const requestIdSuffixB = b.browserRequestId.split('.').length > 1 ? b.browserRequestId.split('.')[1] : b.browserRequestId

We are running into similar issues when we updated from 12.12.0 to 13.6.0.

Can you give an update on a fix for this issue @jennifer-shehane @chrisbreiding @astone123? If a fix is imminent we will wait, otherwise we'll have to downgrade to 13.3.0.

[astone123]

I wasn't actually able to reproduce this locally, but I added a null check that should fix this issue in #28713

[cypress-bot]

Released in 13.6.3.
