This is because when you have “Automatically remove unused assets” enabled, GameMaker still returns removed animation curves in asset_get_ids(asset_animationcurve) but trying to query their info using animcurve_get gives out a slightly malformed struct.

You can either un-tick that checkbox during development or change

function live_api_asset_add(l_name, l_index) {
	// live_api_asset_add(name:string, index:int)
	/// @ignore
	variable_struct_set(live_api_asset_index, l_name, l_index);
}

to

function live_api_asset_add(l_name, l_index) {
	// live_api_asset_add(name:string, index:int)
	/// @ignore
	if (is_string(l_name) && l_name != "") variable_struct_set(live_api_asset_index, l_name, l_index);
}
