App crashing..getting 'room' not defined in console. about chatcord HOT 9 OPEN

In @Ayush909's code you can see a surrounding if conditional that you are missing @Somsubhra1 https://github.com/Somsubhra1/ChatSpace/blob/master/server.js#L72-L82

If that doesn't help, I suggest console logging or using debug to find what properties exist in the user object to ensure that it's not appearing as null or without a room.

Should be io.to(user.room) instead of io.in(user.room).

Still getting the same error.

Was this issue ever solved? I have the exact same issue. I have a feeling the users[] array is not persisting, because whenever I print out the array using .map, I get: id: undefined, username: undefined, room: undefined multiple times. I am going to try to save the array to a file for persistence and see if this works.

There was never a problem in the first place.. I followed the tutorial and it worked fine. Feel free to link your repo

Found the issue, on the client side I was instantiating multiple io() objects. This was opening multiple connections per browser session. The multiple connections created multiple socket.ids which did not work well with return users.find(user => user.id === id); - basically returning undefined
