Angular 9 - Istanbul test coverage report being generated empty

I'm getting an empty report, it's listing the files but it's not filling up the percentages... Any idea on what can be causing it?

Error message:

Handlebars: Access has been denied to resolve the property "statements" because it is not an "own property" of its parent.
