Hi Jeff, thank you for answer.
I have found this: Configuring Jest · Jest
Used following values:
"coverageReporters": ["text", "text-summary","json", ["lcov", {"projectRoot": "/"}]],
Still getting errors, probably due to: Since Jest 25, coverage reports are having a different source path
I am still trying to fix it. I will post an update here once I find one
