Simple Peer on data stream throws process not defined error - reactjs

Question

I am trying to open a data channel using simple peer. I send the signal using Firebase and am able to get the on connect function to fire.
const [thisPeer, setThisPeer] = useState();
const [connectionStatus, setConnectionStatus] = useState(false);
// in a function
var thisPeerT = new Peer({
initiator: false,
config: {
iceServers: iceServers,
},
});
// signaling code
thisPeerT.on("connect", function (data) {
console.log("onconnect");
console.log(data);
setConnectionStatus(true);
});
setThisPeer(thisPeerT);
In the on connect, I set a state hook that triggers a use effect where I create my on data.
useEffect(
function () {
console.log("here");
console.log(roomID);
console.log(thisPeer);
console.log(connectionStatus);
if (roomID && thisPeer && connectionStatus) {
console.log("here2");
thisPeer.on("data", function (data) {
console.log(data);
});
}
},
[roomID, thisPeer, connectionStatus]
);
However, I get the following error when I try to use thisPeer.on("data"...

I have tried placing the on data at various places throughout my code, and regardless of the position, it seems this error occurs. If I call peer.send() on the other peer, it also gives a process is not defined error on the peer that received the data. Does anyone know how I can resolve the error or where I should open the data channel?

I got the same issue but I can do a workaround by using CDN script
<script src="https://cdnjs.cloudflare.com/ajax/libs/simple-peer/9.11.1/simplepeer.min.js"></script>
And here is a code example of how to call it in React
var peer1 = new window.SimplePeer({ initiator: true })
