From 9372f6f842e3f8c0166d68a3a49ccc73a76954ea Mon Sep 17 00:00:00 2001 From: Sean Quah <8349537+squahtx@users.noreply.github.com> Date: Fri, 17 Jun 2022 10:22:50 +0100 Subject: [PATCH] Fix logging context misuse when we fail to persist a federation event (#13089) When we fail to persist a federation event, we kick off a task to remove its push actions in the background, using the current logging context. Since we don't `await` that task, we may finish our logging context before the task finishes. There's no reason to not `await` the task, so let's do that.
