Hyperledger composer playground error on IBM Blockchain Platform

Question

I am trying to learn about hyperledger composer by going through the tutorials. Everything works on the playground so I followed the tutorial and created a cluster with bluemix.

http://184.172.229.160:31080/

I was testing the hosted playground and I notice all transactions, even if deployed with a sample network like trade-network, returns error saying the asset or participant does not exist

Error: Object with ID 'tradingSymbol:ABC' in collection with ID 'Asset:org.acme.trading.Commodity' does not exist

Any advice on troubleshooting the above error?

Answer 1

最可能的解释是您不需要tradingSymbol:前缀，并且您的资产ID仅为ABC 。

Answer 2

Be aware that Composer Playground use, in your case, tradingSymbol:ABC as the ID, so when you try to retrieve an object you must consider the ID like tradingSymbol:ABC .

If you want to use the ID ABC you must erase tradingSymbol:ABC when you create the object using the playground and write just ABC . I know it is a little bit tricky.
