I'm trying to test my headless server made with unity3d to integrate it with the Multiplayer 2.0 version of Playfab using this Unity-specific GSDK and following this guide: https://docs.microsoft.com/en-us/gaming/playfab/features/multiplayer/servers/locally-debugging-game-servers-and-integration-with-playfab. When I run it my server executable crash when the GSDK Start function gets called. It complains about a missing GSDK_CONFIG_FILE environment variable. Because the configuration file is generated dynamically this GSDK_CONFIG_FILE shouldn't also be setup dynamically?
