Error: dynamodb number_value cannot be converted to string
What's Causing This Error
This error message indicates an issue with the data type of an attribute in the item being stored or retrieved in DynamoDB. Specifically, it suggests that a number data type (such as an int or float) is being passed as an attribute value, but the attribute expects a string data type.
Solution: Here's How To Resolve It
To solve this error, check the data types of the item's attributes to ensure that they match the table's schema. For example, ensure that the attribute expecting a string data type is passed a string value.
You can convert the number value to a string before putting the item in the table.
import boto3 # Instantiate a client dynamodb = boto3.client('dynamodb', region_name='us-west-2') # Define the parameters table_name = "my_table" item = { 'primary_key': {'S': '12345'}, 'number_value': {'S': str(number_value)} } # Perform the operation dynamodb.put_item(TableName=table_name, Item=item)
Finally, check that the IAM user or role used to call the function has the necessary permissions to operate on the DynamoDB service.
