I'm not a javascript guru, but seeing the typeof examples shouldn't it be const isString = typeof encodedPackets[0] === "string"; ?

const firstPacketOpts = {
wsPreEncoded: "4" + encodedPackets[0], // "4" being the "message" packet type in Engine.IO
wsPreEncoded: isString ? "4" + encodedPackets[0] : encodedPackets[0], // "4" being the "message" packet type in Engine.IO
...packetOpts
};
