com.apollographql.apollo.exception.ApolloHttpException: HTTP 500 Internal Server Error

Question

I keep getting the HTTP 500 Internal Server Error in my android studio trying to call a loginQuery with apollo client for android, following this tutorial : link to apollo docs

Yet when I run the same query in graphiQL in my browser, it succeeds.

here's a picture of the error in studio :

here's my code:

String userNumber = numberInput.getText().toString();
String password = passwordInput.getText().toString();
Intent intent;

LogInQuery logInQuery = LogInQuery.builder().nationalID(userNumber).password(password).build();
apolloClient.query(logInQuery).enqueue(new ApolloCall.Callback<LogInQuery.Data>() {
    @Override
    public void onResponse(@NotNull Response<LogInQuery.Data> response) {
        LogInQuery.Data data = response.getData();
        List<Error> error = response.getErrors();
        assert error != null;
        String errorMessage = error.get(0).getMessage();

        assert data != null;
        Log.d(TAG, "onResponse: " + data.login() + "-" + data.login());

        if(data.login() == null){
            Log.e("Apollo", "an Error occurred : " + errorMessage);
            runOnUiThread(() -> {
                // Stuff that updates the UI
                loading.setVisibility(View.GONE);
                Toast.makeText(LogInActivity.this,
                        errorMessage, Toast.LENGTH_LONG).show();
            });
        } else {
            runOnUiThread(() -> {
                // Stuff that updates the UI
                loading.setVisibility(View.GONE);
                Toast.makeText(LogInActivity.this,
                        "New User Created!", Toast.LENGTH_LONG).show();

                //Intent intent = new Intent(LogInActivity.this, LogInActivity.class);
                //startActivity(intent);
            });
        }
    }

    @Override
    public void onFailure(@NotNull ApolloException e) {
        runOnUiThread(() -> {
            Log.e("Apollo", "Error", e);
            Toast.makeText(LogInActivity.this,
                    "An error occurred : " + e.getMessage(), Toast.LENGTH_LONG).show();
            loading.setVisibility(View.GONE);
        });

    }
});
}

I can't find much on the internet to help me solve it. If it's duplicate, direct me to the correct answer.

Check your API in Postman. It's working fine or not! Please share API if possible.

here's the api : https://waste-mgmt-api.herokuapp.com/graphql , and I didn't use postman, i used the graphql browser interface, also the api is working fine for other mutations and queries, just not the login one. which is puzzling to say the least – itwabi Feb 24 '21 at 16:40
Use a client that will give you more details for error. As per your data. The issue is. The API you are calling doesn't exist. Refer this post to the client. https://site-valley.com/2021/02/17/retrofit-android-tutorial-in-kotlin/ – Abhnav Maurya Feb 25 '21 at 06:33
