From 42922c1d30488de93cc729582539e26c3b1356eb Mon Sep 17 00:00:00 2001 From: Richard Park <51494936+richardpark-msft@users.noreply.github.com> Date: Thu, 10 Oct 2024 19:52:47 -0700 Subject: [PATCH] [azeventhubs,azservicebus] Applying retry fix to both eventhubs and servicebus (#23562) * Some lint errors. * Fixing some broken tests. It looks like these weren't running in CI because what I've changed should not have affected them at all.
