The jstests/noPassthrough/timeseries/create/timeseries_writes_check_buckets_coll_is_valid.js test uses a failpoint to create a system.buckets collection with invalid options bypassing the usual validations done by createCollection. This is difficult to adapt to the needs of viewless timeseries collections, so we should rather test this with a C++ unit test which allows straightforward manipulation of the collection options from the catalog without depending on failpoints.
