Ack message timeout

[jneums]

First off, thanks for the great websocket implementation!

Second, I'm getting errors consistently that close my connection with the canister. It happens when developing locally using the ICWebsocket repo as well as when running against the hosted version on AWS:

[onAckMessageTimeout] Ack message timeout. Not received ack for sequence numbers: Array(12)

Hi @jneums, could you provide a minimal example or source code?

Is the local gateway printing any warning or errors?

I've just checked that the demo is running as expected, and it's using the AWS gateway.

@ilbertt , no problem! Here is the repo as well as the version running on the IC. The version on the IC stopped connecting this morning when I went to check, but it was connecting fine last night. The demos are working fine though like you said, which is strange.

The local version connects fine still, but has the original [onAckMessageTimeout] issue.

@jneums sorry for the late reply :(

I see you switched to the polling approach instead of WebSockets. I'm really sorry I couldn't provide help in time. I'll try to investigate what's happening anyway and hopefully get back to you.

No worries! Let me know if you figure it out. I'd love to use the websockets. It feels weird polling so frequently from the browser.
