fabric-sdk-go | SDK enables Go developers to build solutions | Blockchain library

I am currently running hyperledger fabric v2.2. I have developed the chaincode using the contractapi and developing the application using fabric-sdk-go/pkg/gateway

How can i get the transaction status and the transaction payload? I am aware of the GetHistoryByKey() which is available in the contractapi but that doesn't works out for my application.

I know there is hyperledger-explorer which can be used to search transactions by TxID but my use-case is my application will be querying by TxID and then it will verify the status of that particular transaction (TxID).

Also, i have tried to achieve this using the fabsdk but i am getting an error when i try to create instantiate the fabsdk using the fabsdk.New(). There seems to be some compatibility issue with the connection-profile.json which i am using the fabric-sample project.

The error which i am getting is:

failed to create identity manager provider: failed to initialize identity manager for organization: MyOrgName: Either a cryptopath or an embedded list of users is required

The same connection-profile has been used in getting the network up and running, and everything seems to be working all good. I am able to submit and evaluate transactions.

SOLUTION

The system chaincodes are embedded in the peer itself. so we need to set the target otherwise it would just give the discovery error since the contract QSCC is not explicitly deployed on the channel.

Make sure to check the core.yaml file channel.system - the system chaincode should be enabled channel.system.qscc: enable
