Right. If staging or the canary is logging errors, you block/abort the deploy. If it’s logging warnings, that’s normal.
Unless it is logging more warnings because your new code is failing somehow; maybe it stopped parsing the reply correctly from a "is this request rate limited" service so it is only returning 429 to callers never accepting work.
