when to unsubscribe this observable?

Hello,
What's the license of this repository? Is only for those who bought the course? Can it be . used for personal learning without buying the course? Can it be referenced in other blog posts / conference talks with attribution/link?

Thanks a lot.

Cheers,

after upgrading rxjs to rxjs 6.3.2 and angular to 6.1.8, I am getting following error, any idea?

When I try to start the application I get the following error message: [HPM] Error occurred while trying to proxy request /api/courses from localhost:4200 to http://localhost:9000 (HPE_INVALID_CONSTANT) (https://nodejs.org/api/errors.html#errors_common_system_errors)

I tried to use another port, and switched localhost for 127.0.0.1 but without success. What can I do about it?
