Not able to generate code coverage report on running vue 3 (typescript) application on a headless mode

[elangoRamar]

Current behavior

I am trying to generate the cypress code coverage report when i run the tests on a headless mode. But it's not generating the report.

And it's creating the report on interactive mode(cypress open -e2e).

Vue project dependency version:
"vue": "^3.4.21",
"vite": "^5.2.7",

And i am using "nyc": "^15.1.0" and "vite-plugin-istanbul": "^6.0.0" to generate the report.

Even i tried adding "@istanbuljs/nyc-config-typescript": "^1.0.2" and .nycrc configuration also not working.

I know there’s some comments in this thread about getting code coverage setup for ct testing, some of it may help you with a workaround. cypress-io/code-coverage#596
