Error: dynamodb text contents could not be decoded

What's Causing This Error

This error message indicates an issue with the text contents being stored or retrieved from the DynamoDB table. Specifically, it suggests that the text contents could not be decoded. This can happen if the text contents are not in the correct encoding format or if there is an issue with the text contents themselves.

How to solve this error:

Check the text contents' encoding format and ensure they match the encoding format expected by the DynamoDB table. In addition, ensure that the text contents are in the correct format and do not contain invalid characters or syntax errors.

You can convert the text contents to the correct encoding format before storing or retrieving it from the DynamoDB table.
