Problem Statement/Rationale

If I follow the instructions here to create an empty sharded timeseries collection on latest master locally:
https://www.mongodb.com/docs/manual/core/timeseries/timeseries-shard-collection/

i.e

sh.shardCollection(   "test.weather",   { "metadata.sensorId": 1 },   {      timeseries: {         timeField: "timestamp",         metaField: "metadata",         granularity: "hours"      }   }) 

I actually don't see the timeseriesFields being set on the doc for the collection in the config.collections collection i.e it's not creating a timeseries collection.

Please be sure to attach relevant logs with any sensitive data redacted.
