Error: error retrieving dynamodb table item serializationexception
Answered by Rafal Wilinski
What's Causing This Error
This error message indicates an issue with the serialization of the item retrieved from the DynamoDB table. This can happen if the item's data types are not correctly defined or the item's data is not in the correct format.
Solution: Here's How To Resolve It
To solve this error, check the data types of the item's attributes to ensure that they are correctly defined and match the table's schema. In addition, ensure that the data is in the correct format and follows the constraints of the data types.
Also, check that the IAM user or role used to call the function has the necessary permissions to perform the desired operation on the DynamoDB service.
You can also try to get the item by providing the primary key and key schema information instead of the attribute value.
import boto3 # Instantiate a client dynamodb = boto3.client('dynamodb', region_name='us-west-2') # Define the parameters table_name = "my_table" key = { 'primary_key': {'S': '12345'} } # Perform the operation response = dynamodb.get_item(TableName=table_name, Key=key)
