RabbitPubSub Queue Connection Closes Unexpectedly with FailedPrecondition Error about go-cloud HOT 2 OPEN

Can you clarify what you mean by "the issue persists"?

From looking at the code, it looks like we "refresh" the channel before using it, but there are definitely cases where the channel could close after that check, and you'd get an error from that operation (e.g., Send or Receive). But, retrying should end up calling establishChannel again, which should reset things unless your actual server is down.

Overall, you're likely going to have to debug this a bit on your own to figure out where the error is being generated. E.g., you could use https://github.com/rogpeppe/gohack to add some logging/printing to the existing code to see when establishChannel is being called, when the error is returned, and what happens when you retry.

HTH!

This is what I mean by the error persists: My code works on my server, but when the channel is not used for a certain period of time (about 1-2 weeks), when I want to send something to the channel again, I get ,

"error=pubsub (code=FailedPrecondition): Exception (504) Reason: "channel/connection is not open".

restarting the app fixes the error. But when it is not used again, it repeats the same bug.
