How to Fix: WebRTC Uncaught InvalidStateError: Failed to execute 'send' on 'RTCDataChannel' without 0.5s sleep
The issue arises from attempting to send data on an RTCDataChannel when its readyState is not 'open'. The 0.5 second sleep in the code allows the readyState to transition from 'closed' to 'open', enabling data sending.
