Firebase – Running cloud function locally from emulator

I am sucessfully running local cloud function from postman with this url:

http://127.0.0.1:5001/spotnik-7de37/us-central1/getUsers

But on my app using:

val functions = Firebase.functions
functions.useEmulator("10.0.2.2", 5001)
functions.getHttpsCallable("http://127.0.0.1:5001/spotnik-7de37/us-central1/getUsers")

I get:
Failed com.google.firebase.functions.FirebaseFunctionsException: INTERNAL

    Need to use HTTPS protocol and not HTTP. See https://firebase.google.com/docs/emulator-suite/connect_functions

    Instrument your app for HTTPS functions emulation Each HTTPS function
    in your code will be served from the local emulator using the
    following URL format:

    http://$HOST:$PORT/$PROJECT/$REGION/$NAME

    For example a simple helloWorld function with the default host port
    and region would be served at:

    https://localhost:5001/$PROJECT/us-central1/helloWorld

    Take a look at Call functions from your app. Just use the name of the function for the getHttpsCallable() call:

    private Task<String> addMessage(String text) {
  // Create the arguments to the callable function.
  Map<String, Object> data = new HashMap<>();
  data.put("text", text);
  data.put("push", true);

  return mFunctions
    .getHttpsCallable("addMessage")
    .call(data)
    .continueWith(new Continuation<HttpsCallableResult, String>() {
        @Override
        public String then(@NonNull Task<HttpsCallableResult> task) throws Exception {
            // This continuation runs on either success or failure, but if the task
            // has failed then getResult() will throw an Exception which will be
            // propagated down.
            String result = (String) task.getResult().getData();
            return result;
        }
    });
}

    In your case I might try the above example using:

    httpsCallable('spotnik-7de37')

    Or use this:

    getHttpsCallableFromUrl("http://127.0.0.1:5001/spotnik-7de37/us-central1/getUsers")

    Also ensure you are using the proper IP for your emulator:

    functions.useEmulator("127.0.0.1", 5001);

    Additionally, if you want to use the entire URL string for the call, you can use getHttpsCallableFromUrl.
