group metadata is null

[ahihi]

hi,

i am using HueApi 1.4.0, as it is the last version with .NET Framework 4.6.1 support.

when i retrieve information about groups like this:

var hue = new LocalHueApi(address, key);
var groupsResponse = await hue.GetGroupsAsync();

i expect to find the group names in the metadata for each group. but i am only getting a null Metadata field for each group. is there something else i need to do to populate this field?
