[ERROR] name=cloudwalk, domain=cloudwalk#run_callbacks: Broken pipe (Errno::EPIPE)

Open kumarsukhani opened this issue 5 years ago • 3 comments

Many times I am getting Broken pipe error because of which the msg sent by the server is not received in Slack channel. How can I fix this issue?

That's generally a broken RTM connection. You could start by replacing say with a chat_postMessage to see if that helps?

@dblock : Thanks. It worked :) Sorry I am using slack-ruby-bot project. Should I move this issue on that project?

ove

Sure. I don't think it's a bug though or not sure what we should do with it. The RTM connection is not 100% reliable, and just like with any connection, it's on the client to retry in case of failure or for us to build retry into the client.
