Error: dynamodb does not accept empty set

What's Causing This Error

This used to be an error that occurred before 20th May 2020. However, if you are running into this error in 2022, it is most likely that you are running on an old SDK version, or you have not enabled empty value conversion in the Document Client.

Solution: Here's How To Resolve It

Firstly, upgrade your AWS SDK to the latest version.

npm i aws-sdk@latest

Hereafter, set the convertEmptyValues property to true when initializing an instance of Document Client, as shown below.

const aws = require('aws-sdk');
const documentClient = new aws.sdk.DynamoDb.DocumentClient({
  convertEmptyValues: true
