To solve this error, you can take the following steps:

  • Ensure that the set is passed as a value for the attribute is not empty and contains at least one element.
  • When creating a new item, you can check if the set is empty and then add an element to it before sending the request to the DynamoDB service.
  • If you're using the AWS SDK, you can check the documentation of the SDK to see if there is any helper function to check if a set is empty.
  • If the issue persists, you may contact AWS support for further assistance.
  • Additionally, you can use CloudWatch logs to check the logs and troubleshoot the issue.
