Answer 1

Seems like you have not added sort key in dynamo db table and the other items have the same primary key as of first item. I faced similar issue and worked after adding sort key.

Answer 2

This seems to be another bug in AWS Amplify or local DynamoDB.

I am using the same schema - when I add even just a space to schema.grapql, first delete operation works. The delete operations executed after are not working.

Also, it seems like something is throttling query response (I am using amplify mock command): E.g. I have 7 items in the database and when I am trying to list all of them, I got responses with 1, 2, or even zero items, multiple times - when I would expect, that they will be loaded in 1 request, at the same time.

I am using AWS Amplify

 "aws-amplify": "^3.1.1",
 "aws-amplify-react-native": "^4.2.5",

Even if you modify schema.graphql, it's still unreliable.
