Unity not instantiated

[i-jared]

I'm trying to add a listener in react that triggers a sendMessage back to unity (after fetching some data). Whenever the listener is activated and sendmessage is called, it gives me an error saying that unity is not instantiated yet. However, when I make a button to call sendmessage like the example, it works fine.

Any idea how I can fix this?
