Thanks for getting back so quickly!
I triple-checked and I definitely have everything that the error message is asking for. I ended up fixing my issue after poking around in the source code and finding the variables live_gmlive_asset_api_blank_object and live_gmlive_asset_api_blank_room; I used those in the create event and it started working.
live_init(1, "http://localhost:5100", "");
live_gmlive_asset_api_blank_object = obj_blank
live_gmlive_asset_api_blank_room = rm_blank
