413 Payload Too Large Error When Using Chatbot Share Button in Multistep Agent UI

[yvrjsharma]

Describe the bug

Using the share button in the open-deep-research chatbot component triggers a 413 (Payload Too Large) error from CloudFront.

This happens when trying to share agent response (usually with more than four agent steps) to Hugging Face Spaces Discussions using the share button. However, no error occurs if the agent response is small.

Error Message

413 ERROR
The request could not be satisfied.
Bad request. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error.

Suggested Solutions

1. It would be helpful to have either built-in handling for large payloads or adding docs about size limitations for the share functionality.
2. Can we add a gr.Warning when content exceeds the shareable limits
3. One possible solution could be to offer a configurable parameter that allows sharing only the last N messages. However, if the agent's response is too lengthy for certain chats, sharing with N=1 might still result in a 413 Error.
