Error When Using GetOwnedGames on MacOS

[alexp9982]

When using MacOS (On Windows, the exact code works just fine), when attempting to use the GetOwnedGamesAsync method, the method fails and shoots an AutoMapper error. Here is the error stack:

AutoMapper.AutoMapperMappingException: Error mapping types.

Mapping types:
OwnedGamesResult -> OwnedGamesResultModel
SteamWebAPI2.Models.SteamPlayer.OwnedGamesResult -> Steam.Models.SteamCommunity.OwnedGamesResultModel

Type Map configuration:
OwnedGamesResult -> OwnedGamesResultModel
SteamWebAPI2.Models.SteamPlayer.OwnedGamesResult -> Steam.Models.SteamCommunity.OwnedGamesResultModel

Destination Member:
OwnedGames

Is this issue possible to solve on your end or is this an AutoMapper problem?
