[BUG] uploading a too large file as full file upload is not raised in the chat as an error

[bodzebod]

Describe the bug
When enabling full file upload in an agent flow, I can upload a file for asking questions about it.
However, if the context size appears to be too large, nothing is raised to the chat, i.e no error and no message. The chat just stops with no response. However, in the logs, I can see the error.

To Reproduce
Steps to reproduce the behavior:

1. Create an agent flow with a supervisor, a worker, and their dependencies
2. Configure the agent flow to enable full file upload
3. Upload a large text file to the chat
4. Ask a question about it

Expected behavior
If an error is raised internally, it should be also raised to the chat so that the user can be aware that there is a technical issue.

Screenshots
See in the chat, there's no response:

But there is an error "string too long" in the logs:
