DynamoDB Item size to update has exceeded the maximum allowed size

[nchan1994]

Describe the bug
Have set up a DynamoDB as data source with S3.
Normal messages without uploading files works just fine.

When uploading an image of any size, the current DynamoDB package in Chainlit tries to save the img file bytes content along with the user message into DynamoDB table, triggering a Boto3 DynamoDB Client error.

To Reproduce
Steps to reproduce the behavior:

*After setting up DynamoDB table and S3, and configuring Chainlit App to leverage those as data source.

1. Start a new chat
2. Click on Attachments
3. Upload file (png/jpeg) of any size (e.g. 500MB)
4. Type a prompt
5. Send
6. Check terminal for Boto3 error

Expected behavior
Expected is that the DynamoDB should put_item of the user message and the S3 URL of the image file uploaded.
