Subscribe is deprecated: Use an observer instead of an error callback

by

subscribe isn’t deprecated, only the variant you’re using is deprecated. In the future, subscribe will only take one argument: either the next handler (a function) or an observer object.

So in your case you should use:

.subscribe({
   next: this.handleUpdateResponse.bind(this),
   error: this.handleError.bind(this)
});
