aws-sdk-ruby: DynamoDB #query method returns response with items = nil

Describe the bug

Initial issue (https://github.com/Dynamoid/dynamoid/issues/516) was reported in Dynamoid project. It seems the #query (link) method may return sometimes response with #items equal nil.

Expected Behavior

I would expect QueryOutput#items to return Array of items or at least an empty Array if there are no items to fetch as the documentation states.

https://docs.aws.amazon.com/sdk-for-ruby/v3/api/Aws/DynamoDB/Client.html#query-instance_method

Current Behavior

QueryOutput#items returns nil

Reproduction Steps

There is no way to constantly reproduce the issue. The issue is being reproduced occasionally.

Possible Solution

No response
