Coding Help

I'm going through this tutorial in building a real time web chat using react and firebase to help me with my NEA (https://www.youtube.com/watch?v=k4mjF4sPITE) and I got up to roughly 1 hour through and I get this error which I don't know how to fix. I get it when I open the server from vscode straight away

Any advice on how to fix it or links you can guide me to? (I tried researching this error myself but I don't think the solutions i found online like on stackoverflow and github apply to my code so I'm very confused)
