Angular2 Http with RXJS Observable TypeError: this.http.get(…).map(…).catch is not a function

Question

I have following Service which was working fine until today i got this error

TypeError: this.http.g         


        

Answer 1

It seems that the catch operator isn't imported.

You could try to import it like this:

import 'rxjs/add/operator/catch'

Or more generally this if you want to have more methods for observables:

import 'rxjs/Rx';
