Я новичок в AWS Amplify и пытаюсь следовать приведенной здесь документации. Все отлично работают с приведенным ниже кодом:

  try {
     Amplify.addPlugin(new AWSApiPlugin()); //Giving error when inserted
     Amplify.addPlugin(new AWSDataStorePlugin());
     Amplify.configure(getApplicationContext());

     Log.i("Tutorial", "Initialized Amplify");
 } catch (AmplifyException e) {
     Log.e("Tutorial", "Could not initialize Amplify", e);
 }


Todo item = Todo.builder()
   .name("Build Android application")
   .description("Build an Android application using Amplify")
   .build();

 Amplify.DataStore.save(item,
     success -> Log.i("Tutorial", "Saved item: "   success.item().getName()),
     error -> Log.e("Tutorial", "Could not save item to DataStore", error)
 );
 

Но когда я добавлял Amplify.addPlugin(new AWSApiPlugin()); внутри try/catch и снова запускал приложение, оно всегда выходило из строя и выдавало мне эту ошибку.
