Websocket OnMessage not trigger when change layout

I have game using websocket then have 3 message like 'a','b','c'. When game get message 'a', game must change layout to 'ingame' layout.

But the problem is after game change layout to 'ingame', websocket just trigger on message 'c'. If game not change layout, game will get all the message.

Which i think that bug when on change layout websocket on message will not trigger.

What should i do ?

Check which event sheets all the layouts involved use. If a layout does not use an event sheet with a trigger on it, either directly or by event sheet includes, then that trigger won't fire.

All layout and main event sheets already included the websocket event, and that bug sometimes trigger and sometimes doesn't trigger when change layout.

Should i make script js for websocket for always run on background ? or how to make event sheet always run in background ?
