Block sending empty messages to chat endpoint

[adamjarling]

What does this do?

Handles a scenario where empty search values were being passed to the endpoint (causing issues in the API). The Chat component now guards against this by checking for a search term value.

How to test

1. Open the Network tab of your browser and navigate to the Websocket (WS) tab to inspect traffic.
2. Try searching with Gen AI enabled with both empty and non-empty search terms.
3. Notice in the websocket logs, the question property will never be an empty string.

For developers, you can also do a quick console log, or put a breakpoint in this function to check as well:

dc-nextjs/hooks/useChatSocket.ts

Lines 63 to 67 in a6ddf55

	const sendMessage = useCallback((data: object) => {
	if (socketRef.current && socketRef.current.readyState === WebSocket.OPEN) {
	socketRef.current.send(JSON.stringify(data));
	}
	}, []);
