Question: How to handle empty strings in DynamoDB?

Rafal Wilinski

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.
