Error: DynamoDB could not invoke null on class

Answered by Rafal Wilinski
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.
