There are various issues with your implementation.

Issues with the save method:

1. You're using async which only works on methods that return a promise.
2. You're calling validate method on the myService in the callback method, which returns an Promise Observable.
3. You could've used used await in there if the validate method returned a Promise. But it returns an Observable.
4. forEach runs synchronously but the myService.validate method runs asynchronously and so will the callback method inside the success callback to the .subscribe method.

That's the reasons why it's logging '1st After for loop' before logging the results.

Issue with the async save method:

You're awaiting the new Promise inside the method but not rejecting or resolveing that promise.

That's probably why the '2nd- After for loop' isn't even logging.

A better way would be to either use the RxJS forkJoin operator to join all the Observables returned by the myService.validate method and then log inside the success callback to the subscribe method. Something like this:

In your proxy configuration file, you are setting up the proxy for your http://localhost:4200/api*. So, the proxy will not work for /getPerson
