Steps to Reproduce
I attached here a short Angular 6 project. Here is the instruction how to re-produce the issue:
poc-kafka-typescript.zip

Install NodeJs 10.1.0
Install Angular CLI by running: npm install -g
extract the attached zip file
cd poc-kafka-typescript
npm install
ng serve --open
You will get this log in command line:
