Error: DynamoDB Missing Authentication Token

What's Causing This Error

The most frequent cause for this error is trying to access a DynamoDB table without providing proper credentials.

Solution: Here's How To Resolve It

When making requests to DynamoDB, ensure that you have included the appropriate AWS access key and the Secret key in the request to prevent this error from occurring. Alternatively, you can use IAM roles and policies to grant table access. Ensure that you have specified the correct region when creating the DynamoDB client.

Also, check whether the IAM role you use has the necessary permissions to perform the operations you are trying to perform on the DynamoDB table by reviewing the IAM policies for the user.
