From 563a46594fc913303b9f81b45dfe045ff306c7e5 Mon Sep 17 00:00:00 2001 From: Owl Bot Date: Wed, 16 Feb 2022 20:49:01 +0000 Subject: [PATCH 1/2] fix!: annotating some fields as REQUIRED These fields were actually always required by the backend, so annotation just documents status quo. I believe this change will not require major version bump for any language.
