Error: dynamodb value cannot be null. (parameter 'type')

Answered by Rafal Wilinski
What's Causing This Error
This error message indicates an issue with passing a null value for the 'type' parameter when working with the DynamoDB service.
Specifically, it indicates that the value passed for type cannot be null. This can happen if the code is trying to pass a null value for the type parameter when making an API call to DynamoDB or if there is a bug or an issue with the code that is causing the null value to be passed.
Solution: Here's How To Resolve It
To solve this error, check the code where the type parameter is being passed and ensure that it is not passed as a null value. Instead, pass a valid value for the 'type' parameter when making an API call to DynamoDB.
