Error: DynamoDB is missing the key id in the item

Rafal Wilinski

Answered by Rafal Wilinski

What's Causing This Error

This error is caused by a missing primary key in the item inserted or updated in the DynamoDB table. Every item in a DynamoDB table must have a primary key, which is used to uniquely identify each item and determine the item's physical location in the table. In this case, the primary key is missing in the item being inserted or updated.

Solution: Here's How To Resolve It

To solve this error, you need to ensure that the item inserted or updated in the DynamoDB table has a primary key.

The primary key should be included in the item as an attribute with the name id . Also, you should check if you have defined the primary key in the table schema. If you haven't done that yet, you need to define the primary key while creating the table, or you can update it via the update-table command. You can also make use of the put_item() or update_item() functions provided by the AWS SDK for Python (Boto3) to insert or update items in the table, respectively, which will automatically handle the inclusion of the primary key in the item.
