Get metadata for a single Feature. Note this endpoint is incompatible with Full Stack Targeted Rollouts projects
(default in accounts created after July 2020) and with non-legacy Full Stack projects (default in projects created after February 2021).
See the compatible API at https://library.optimizely.com/docs/api/flags/v1/index.html#tag/Flags.
If you are using a Targeted Rollouts Legacy application account, we only support creation of Features via this API endpoint, we do not support updates or management of Targeted Rollout rules.
For full support for API-management of Feature Flags and Rollouts, you will need to use a new Flags Application Project or wait for migration of your existing Legacy projects to Flags.
