In the [V3 API](GET /repos/:owner/:repo/milestones) it is possible to do the following request:
On this endpoint, you can then perform filters on the milestones based on a provided parameters e.g. state = open , closed or all.
What is the equivalent of this in the V4 GraphQL API i.e. retrieving only OPEN milestones on a repository?
After some further research, this isn’t possible yet but it will be possible after changes are made following this schema request raised in the platform community in November 2017.
