Karma fails with coverage reports

[AhmedHadjTaieb]

Expected behaviour

I use jasmine with karma to my unit tests for project angular cli and I need the report of coverage. But when I use coverage and coverage-istanbul I found error.

Actual behaviour

karma start ./karma.conf.js

With webpack if it works for me if I use a more simplified form of sourcemaps or turn them off altogether
