Error calling function.

I'm trying to create a project with firebase, I have this code to see if the user is logged in. If it's logged in, I want it to call this function that's in the event sheet.

function verConexao(runtime){ 
	const user = auth.currentUser;
	if (user) {
		runtime.callFunction ('trocarAnimacao');
 		//alert("Você está logado");
	} else {
 		//alert("Você não está logado");
		}
} 

this error appears in the browser console.

I've already figured out what the mistake was. I forgot to put the runtime when calling the function in the event sheet.

That's how it works
