Observable and Http errors

See original GitHub issue

Can anybody explain me the mechanism of error handling? For example, I have 2 subscribers on one observer

  let observable = this.authService.signIn(formGroup.value.email, formGroup.value.password);
  
  // 1st subscriber
  observable.subscribe((response: SignInResponse) => {
    console.log('First - Success');
  }, () => {
    console.log('First - Error');
  }, () => {
    console.log('First - Finally');
  });
  
  // 2nd subscriber
  observable.subscribe((response: SignInResponse) => {
    console.log('Second - Success');
  }, () => {
    console.log('Second - Error');
  }, () => {
    console.log('Second - Finally');
  });`

If I get 400 from the server - both error messages First - Error, Second - Error appears as expected, but if I remove error and finally callback for the first subscriber as

  let observable = this.authService.signIn(formGroup.value.email, formGroup.value.password);
  
  observable.subscribe((response: SignInResponse) => {
    console.log('First - Success');
  });

  observable.subscribe((response: SignInResponse) => {
    console.log('Second - Success');
  }, () => {
    console.log('Second - Error');
  }, () => {
    console.log('Second - Finally');
  });

I don’t get the error callback of the second subscriber
