One or more parameter values were invalid: An AttributeValue may not contain an empty string

See original GitHub issue

I’m experiencing the following error when one of my fields is an empty string:

One or more parameter values were invalid: An AttributeValue may not contain an empty string (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ValidationException;

I was very surprised to discover that DynamoDb doesn’t support empty strings. Is it supposed to work out of the box with Scanamo? Is there a way to configure Scanamo/provide a string format to work around this issue?

You have no idea 😩 We could change the string encoder to use null there, see if it fixes the issue.
