Error: dynamodb unable to find storage information for property

Answered by Rafal Wilinski

What's Causing This Error

This error message indicates that DynamoDB cannot find the storage information for a specific property in the item being written to the table. This can happen if the property is not defined in the table's schema or if the property's data type is incompatible.

Solution: Here's How To Resolve It

To solve this error, ensure that the property and data type is defined in the table's schema. You can check the schema by calling the describe_table method or the table's definition in the AWS Management Console.

Here is an example of how to check the schema of a table:

import boto3

# Instantiate a client
dynamodb = boto3.client('dynamodb', region_name='us-west-2')

# Define the parameters
table_name = "my_table"

# Perform the operation
response = dynamodb.describe_table(TableName=table_name)


Ensure that the property is added or updated in the correct format and data type.

Additionally, check if the IAM user or role used to call the function has the necessary permissions to perform the desired operation on the DynamoDB service.
