gcf-owl-bot[bot] · feywind · commit ee09b69092a1 · 2023-08-30T15:53:23.000-04:00
* fix: simplify logic for HTTP/1.1 REST fallback option For the `fallback` parameter, all values considered as `true` in Boolean context will enable HTTP/1.1 REST fallback, since the other fallback transport, proto over HTTP, is removed from `google-gax` v4.
