I have the same issue. Does any one have a workaround or solution?

[zhongzi]

+1, any ideas now?

My code base also occasionally experiences the "Protocol error: Connection closed. Most likely the page has been closed." error message. The code uses a timeout of 10000 ms. Would it be advisable to update to a timeout of 30000 ms? Any other ideas?

Would it be advisable to update to a timeout of 30000 ms?

PR will be welcome.

I also experienced the same problem, which was fixed after adding heartbeat event listening after robot instantiation, as shown in the following code example:

const robot = new Wechaty()
......
.on('heartbeat', onHeartbeat)
.......

 function onHeartbeat(str: any) {
    console.log(`test heartbeat: ${str}`)
}

@frlute I have to say that, I believe whether you add a listener to the heartbeat event or not, will absolutely have no effect to the Wechaty system.
