What's Causing This Error

This error message indicates a validation error with the data being passed to the DynamoDB service, preventing the operation from being completed.

Several things, such as an issue with the data type of an attribute, a problem with the size of an attribute, an issue with the format of an attribute, or an issue with the primary key of an item, could cause the specific error.

Solution: Here's How To Resolve It

To solve this error, check the data being passed to the service to ensure that it is in the correct format and data type. In addition, ensure that the primary key of the item being written to the table is unique and that the size of the attributes being written does not exceed the maximum size limit of 400KB.
