I just had a similar issue in my own personal starter (which is heavily inspired by this one). For me it was fixed to changing the istanbul-instrumenter-loader back to 0.2.0.

[nekkon]

Changing istanbul-instrumenter-loader back to 0.2.0. didn't work for me :(

[ClemensSchneider]

This should definitely be fixed as in the current state, coverage-reports are not working properly. Reverting instanbul-instrumenter-loader to 0.2.0 worked for me, too.
Seems like it's related to webpack-contrib/istanbul-instrumenter-loader#29

@miguelramos @eXaminator @nekkon @ClemensSchneider - For the sake of keeping discussion in the same place, I am going to close this in favor of continuing the discussion in #1188

I'm working on solving this problem, any further insights please comment in the issue above.

@eXaminator - Unfortunately just locking istanbul-instrument-loader to v0.2.0 only works in certain instance & not in #master for this repo.

[donvadicastro]

Setting strict "0.5.0" version for "karma-remap-istanbul" package helps me.
