Question: How to handle empty strings in DynamoDB?

Answered by Rafal Wilinski
Answer
Since 2020, DynamoDB has supported empty string values for non-key attributes.
Before passing an empty string as a field value, you can set the configuration file IsEmptyStringValueEnabled = true
in DynamoDBContextConfig
class. Or, you can edit the AWS configuration as shown below.
const documentClient = new AWS.DynamoDB.DocumentClient({ convertEmptyValues: true });
You can refer to this documentation for more details.
