I am trying to generate the html reports for my es6 code and receive the following error.

+1 - I get this when transpiling typescript and piping it to istanbul

same issue. you can reproduce it with my open source app at this commit: https://github.com/moribellamy/graytabby/tree/bfd1a7bf5426e6169d95cbeed4266a5ed26bd462

npm run test:coverage gives good enough lcov data, but the HTML report has the error @tomrosier gives above
