I don't think we should error when the user submits. Instead, the input field should not allow more than maxContentSize characters.

This can be a simple indicator of maxContentSize - userInput.length and set the onChange to ignore extra characters beyond maxContentSize

That way, this will never be necessary. From UX perspective, it's easier for the user to edit their message before sending in order to fit the character limit, as opposed to having to copy and paste their previous message and send it again. Not to mention, if you do it like this, there will be a mismatch between the conversation history stored in the FE state with the one stored in the DB

You are right;
it is more intuitive to do let the user trigger this in the first place;
this also pollute the chat history, making it less readable.
