CodePudding user response：

If you want to delete an item, you have to specify the entire primary key. In the case of a table with a composite key, that means both partition and sort keys are required.

From documentation for DeleteItem - Key attribute:

For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.
