Error: One or more parameter values were invalid: some AttributeDefinitions are not used

An error appearing when trying to create a table with a AttributeDefinitions argument containing unnecessary and unused Attribute definitions. Since DynamoDB is schemaless you don't have to and you shouldn't specify attributes for non-key attributes.

Per AWS Documentation:

AttributeDefinitions - An array of attributes that describe the key schema for the table and indexes.

Solution: Don't include any non-key attribute definitions in AttributeDefinitions. Include only Attributes used by the table index or other Global or Local secondary indexes.
