- Do you have any custom NYC settings in `package.json` (`nyc` object) or in other [NYC config files](https://github.com/istanbuljs/nyc#configuration-files)? **No**
- Do you run Cypress tests in a Docker container? **No**
**Describe the bug**
NYC reports and counters are generated but the code coverage HTML file is empty. The window.__coverage__ object is present.
