Error: DynamoDB could not invoke null on class

What's Causing This Error

The error is caused when you are trying to call a method on an null object. This means that the object you are trying to call the method on is not instantiated or has not been initialized.

Solution: Here's How To Resolve It

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

• Check if the object you are trying to call the method on has been instantiated or initialized before calling the method.
• Ensure that the object is not null before calling the method.
• Verify that the SDK being used is configured correctly and that all necessary dependencies are installed.
• Check the Lambda function's code for any syntax or logical mistakes.
• 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.
• It is important to check the state of the objects before calling methods on them to avoid this error.
