Error: dynamodb unable to locate property for key attribute

Rafal Wilinski

Answered by Rafal Wilinski

What's Causing This Error

This error message indicates an issue with the key attribute specified when accessing a specific item in a DynamoDB table.

Specifically, it indicates that the system cannot locate the property for the key attribute. This can happen if the key attribute is not specified correctly in the code, the key attribute does not match the attribute name in the table schema, or the item with the specified key attribute does not exist.

Solution: Here's How To Resolve It

To solve this error, check the key attribute specified in the code and ensure that it matches the attribute name in the table schema. For example, in DynamoDB, a key attribute is made of a partition key and an optional sort key.

You can check the table's schema by running the following command:

aws dynamodb describe-table --table-name 

You can use the get_item() method to check if an item with the specified key attribute exists in the table.

response = table.get_item(
    'partition_key': 'partition_value',
    'sort_key': 'sort_value'
