This is a message from the daily scheduled checks. |
We got another report of the `Puma::ConnectionError` error being reported when upgrading our Ruby gem. The error cause is always the already ignored `Errno::EPIPE` error. It is reported by our response body wrapper that's called when instrumenting response bodies. In this case the error was: Puma::ConnectionError: Socket timeout writing data The cause of this error was this error: > Errno::EPIPE: Broken pipe This doesn't look like an error people can act on to fix it, let's ignore it instead. Related issue appsignal/support#315
I noticed I broke something earlier while writing the previous commit in the close method, but it didn't fail any specs. That's because there weren't any for the error reporting. Add these errors so we can be sure it works.

Traverse the error causes tree to see if any nested error cause is ignored.
