Jest coverage report in html missing coverage values

Question

I am unit testing my ReactJS app with Jest and have added configuration to get the code coverage. The coverage works well on cli but when I try to export coverage report as html the values corresponding to each file are not shown in the report. Here is my jest.config.json:

{
    "roots": [
        "test"
    ], 
    "collectCoverage": true,
    "coverageReporters": ["text","html"],
    "coverageDirectory": "<rootDir>/coverage/"
}

And here is my report generated in coverage folder inside index.html file:

As can be seen the numbers are missing. What coud be the reason when the text report has correct values shown as well. It happens only with html report.

Answer 1

I had this as well. Updating the package istanbul-reports to the latest version (3.0.0 at the time) fixed the issue.
