Error: dynamodb does not support null values
Answered by Rafal Wilinski
What's Causing This Error
Earlier, DynamoDB did not allow you to store empty strings or null values in an item. If you do so, DynamoDB will throw an error indicating that it does not support null values.
Solution: Here's How To Resolve It
However, as of 18th May 2020, DynamoDB no longer runs into this error and has introduced support for null values. Although, keep in mind that you may still run into this error if you are trying to store a null value on an attribute that acts as the partition key for the table or GSI.
