zcy@ubuntu:~/myApplication/FoodSupplyChainDemo$ composer-rest-server
? Enter the name of the business network card to use: admin@foodsupplychain
? Specify if you want namespaces in the generated REST API: never use namespaces

Possible error in consume func

The consume function should make changes to asset registry of steak and should update (AssetToConsume) not resturant
`

@param {org.supplychain.food.model.Consume} param - model instance
@transaction
*/
async function ConsumeFunction(param) {
let assetToConsume = param.liveAsset;
let restaurant = param.atRestaurant;
let factory = await getFactory();

assetToConsume.assetStatus = "CONSUMED";

const restaurantReg = await getAssetRegistry(namespace + '.LiveAsset');
await restaurantReg.update(restaurant);

// emitting Sold event

let consumedEvent = factory.newEvent('org.supplychain.green.model', 'AssetConsumed');
consumedEvent.liveAsset = assetToConsume;
consumedEvent.endGHG = assetToConsume.aggregatedGHG;
await emit(consumedEvent);
}
`
