Cannot find property of undefined

I ma using this library for outputting some coverage in e2e tests with Protractor: ' The message that I get when executing the tests is that it cannot find the outdir property of undefined in teh index.js file inside the node module that generates this library. So probably its deprecated and should be changed but I dont know what to do. Has anybody used this library? I would appreciate some former experience with this or with any better idea for Protractor coverage.

Thanks
