Colyseus.js error after migrating from 0.09 to 0.10

I just migrated colyseus from 0.09 to 0.10. I am getting the following error:
colyseus.js: server error: no available handler for "1mnyb24wwjtwkdbld"

Is there a link to the latest colyseus.js file? I'm using a colyseus.js file from a deprecated project that was posted online, and I don't know how to get the latest version of the colyseus.js file.

hey @henrydavidzhu, you can always find the latest colyseus.js file here: https://github.com/colyseus/colyseus.js/tree/master/dist

colyseus.js: server error: no available handler for "1mnyb24wwjtwkdbld"

This error means you're trying to join a room handler named "1mnyb24wwjtwkdbld" that doesn't exist. You must register the room handler in the server.

gameServer.register("1mnyb24wwjtwkdbld", YourRoomHandler)
class YourRoomHandler extends Room {
// ...
}

I highly recommend you read the documentation:
