cy.task() doesn't work with new Cypress version 12.15.0

[Pavel-Lahutsin]

Current behavior

With the latest Cypress version 12.15.0 cy.task() is broken. It says "cy.task() must only be invoked from the spec file or support file."

Desired behavior

It should work as in previous Cypress version

Test code to reproduce

cypress.config.js

const { defineConfig } = require('cypress')

module.exports = defineConfig({
  // setupNodeEvents can be defined in either
  // the e2e or component configuration
  e2e: {
    setupNodeEvents(on, config) {
      on('task', {
        log(message) {
          console.log(message)

          return null
        },
      })
    },
  },
})

spec.cy.js

describe("Test for bug ", () => {
    it(`should be working`, () => {
        cy.task('log', 'This will be output to the terminal')
    })
});

Getting this too, seems like major issue

Further to this, it breaks stuff like the cypress code coverage lib because that uses cy.task() in an afterHook

[elGatoMantocko]

It looks like this is also breaking cypress-localstorage-commands as well. We are seeing errors when invoking cy.saveLocalStorage() from that lib.

CypressError: `cy.task()` must only be invoked from the spec file or support file.

Locking our cypress version to 12.14.0 allows our tests to run.

Hi everyone. We're aware of this issue and are looking into it now. Until a fix is identified, tested, and released you can temporarily downgrade to Cypress v12.14.0 which does not exhibit this issue.

Issue in 12.5.0 and 12.4.0 as well for cy.readFile()

Works: Older version of node.js also does not work

Released in 12.16.0.
