• Is there .nyc_output folder? Is there .nyc_output/out.json file. Is it empty? Can you paste at least part of it so we can see the keys and file paths? All entries seem to looks the same with the form:

   "/home/camille/xdev/xxx/src/components/somefolder/SomeComponent.vue": {
     "path": "/home/camille/xdev/xxx/src/components/somefolder/SomeComponent.vue",
     "statementMap": {},
     "fnMap": {},
     "branchMap": {},
     "s": {},
     "f": {},
     "b": {}
   },
  

• Do you have any custom NYC settings in package.json (nyc object) or in other NYC config files

   {
     "extends": "@istanbuljs/nyc-config-typescript",
     "all": true,
     "include": [
       "src/**/*.js",
       "src/**/*.ts",
       "src/**/*.vue"
     ],
     "exclude": [
       "**/types/*.ts",
       "**/types.ts",
       "**/*.d.ts",
       "**/*.spec.js",
       "**/*.spec.ts",
       "**/fixtures/*",
       "src/boot/*"
     ],
     "sourceMap": false,
     "instrument": false,
     "extension": [".js", ".ts", ".vue"],
     "report-dir": "test/cypress/coverage",
     "temp-dir": "test/cypress/coverage-cypress-output",
     "reporter": ["json", "text-summary", "lcov", "cobertura"]
   }
  

• Do you run Cypress tests in a Docker container? no

Describe the bug When running any test on my computer, even if the test seems to conclude properly, I get a failure and the following log:

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

Because this error occurred during a after each hook we are skipping all of the remaining tests.
node_modules/@cypress/code-coverage/support.js:20:1
  18 | 
  19 |   // stringify coverage object for speed
> 20 |   cy.task('combineCoverage', JSON.stringify(totalCoverage), {
     | ^
  21 |     log: false
  22 |   })
  23 | }

This works fine with cypress version 12.14; is there some specific thing to change, I have not seen anything specific related to this in the cypress changelog

This seems to fail both with chrome and chrome headless mode.

Link to the repo I’m not sure this is entirely necessary, but if it is let me know and I will try to provide something.
