Fabric Composer test code not working
I have just replaced the sample Composer sample ("sampleAsset", "sampleTransaction", etc.) with another one I created for my better understanding. Everything works except for the transaction, which returns me an error message: "** Error: Could not find any functions to execute transaction org.acme.sample.CompraDoVinho # ** 2b2d0624-bc ..."
Find below source codes:
Blockquote
Model file:
namespace org.acme.sample
Vinho assets identified by IDvinho {
o String IDvinho
--> Participante owner
o String uva
o String nomeVinho
o Integer preco
}
Participant Participant identified by IDparticipante {
o String IDparticipante
o String tipo
o String nomeEmpresa
}
CompraDoVinho transaction identified by IDcompra {
o String IDcompra
--> Vinho asset
o Integer precoVenda
}
Logics:
function onSampleTransaction (CompraDoVinho) {
CompraDoVinho.asset.preco = CompraDoVinho.precoVenda;
return getAssetRegistry('org.acme.sample.Vinho')
.then(function (assetRegistry) {
return assetRegistry.update(CompraDoVinho.asset);
});
}
Access rights:
rule Default {
description: "Allow all participants access to all resources"
participant: "ANY"
operation: ALL
resource: "org.acme.sample"
action: ALLOW
}
Blockquote
Can someone help me find where the error is in my code?
Thank you in advance

The problem is almost certainly due to the fact that you renamed the transaction. Composer has 2 mechanisms for routing transactions for JS functions:
- (Legacy) using a naming convention
onMyTransactionType
. That is, the function is called when the instance is dispatchedMyTransactionType
. - (preferably) using annotations
@transaction
and@param
. Below is an example. The annotation@transaction
indicates that the function would like to process transactions, and the annotation is@param
used to indicate the type of transaction to process.
/ **
* Place an order for a vehicle
* @param {org.acme.vehicle.lifecycle.manufacturer.PlaceOrder} placeOrder - the PlaceOrder transaction
* @transaction
* /
function placeOrder (placeOrder) {
console.log ('placeOrder');
let factory = getFactory ();
let NS = 'org.acme.vehicle.lifecycle.manufacturer';
let order = factory.newResource (NS, 'Order', placeOrder.transactionId);
order.vehicleDetails = placeOrder.vehicleDetails;
order.orderStatus = 'PLACED';
order.manufacturer = placeOrder.manufacturer;
// save the order
return getAssetRegistry (order.getFullyQualifiedType ())
.then (function (registry) {
return registry.add (order);
});
}

Please replace the code in your file logic.js
with the following code and the error will surely go away. My problem was the same problem, I just added the required one JS doc annotations
above the function and the same problem was solved!
'use strict';
var NS = 'org.acme.sample';
/**
* @param {org.acme.sample} CompraDoVinho
* @transaction
*/
function onSampleTransaction(CompraDoVinho) {
CompraDoVinho.asset.preco = CompraDoVinho.precoVenda;
return getAssetRegistry('org.acme.sample.Vinho')
.then(function (assetRegistry) {
return assetRegistry.update(CompraDoVinho.asset);
});
}
Hope this helps you!

Quite right. Annotation is important for the function to work! @param must specify the name of the transaction class and the name of the @transaction parameter declared below, with the function to follow in the block below
@param {org.acme.mynetwork.Foo} foo - report to be processed * @transaction
