Unhandled promise rejection in circleci/cypress tests

Question

I have built a pipeline on circleci, however, i'm getting a build failure with this information:

Error: The following error originated from your application code, not from Cypress. It was caused by an unhandled promise rejection.

I can, however, run this test in cypress no problem with no failures - is there something I am missing in circleci? Thanks,

Answer 1

This means that your application is generating an exception and you should look into that. In case its something that can be ignored, you can go to cypress/support/index.js and add this:

Cypress.on('uncaught:exception', (err, runnable) => {
  // returning false here prevents Cypress from
  // failing the test
  return false
})
