Issue #
Resolves #1596
Description of changes
This change corrects an oversight in key field conversion, namely relying on
ItemConverterimplementations to respect and properly handle theonlyAttributesargument. Given that implementations may vary widely and come from untrusted/unmodifiable sources, this change manually trims post-conversion key fields to retain only key attributes (dropping non-key attributes). Currently this affects four parameters:DeleteItemRequest.keyGetItemRequest.keyQueryRequest.exclusiveStartKeyScanRequest.exclusiveStartKeyThis should eliminate service errors when sending too many fields in the above operations requests.
