Hi, when I tried to create a new member and using it to sign in, however the browser throws this error:

And the Node console gives:

I'm using nodejs version 8.9.4 if that helps.

I am getting the following error

The pre req for the version of vscode to use should now be 1.36 to work with the latest version of the extension

I've been struggling with this error and have no clue how to fix it.

Can anyone help?

Hi Team,
I am facing the below issue while deploying smart contact.

can anyone has cracked it? or help me out to go further.

yo is no longer needed as a prereq for the vscode extension to work

Hello Mate,,

Could you update repository name . It looks like you have updated repository name but in wiki it has old repo name.

current : git clone https://github.com/IBM/customer-loyalty-program-hyperledger-fabric.git
should be : git clone https://github.com/IBM/customer-loyalty-program-hyperledger-fabric-VSCode.git

Thanks

The application has a few references to Composer remaining:

• about.html - it does not use the Composer API, but the fabric network API
• index.html - same as above

Could be confusing to new users.

Hi Ashutosh,

I followed same steps as followed by you but i am stuck at step of adding new member registration and partner registration. While creating new member for the first time i am getting below error :

fabric-ca request register failed with errors [[{"code":19,"message":"CA 'ca.example.com' does not exist"}]]
fabric-ca request register failed with errors [[{"code":19,"message":"CA 'ca.example.com' does not exist"}]]

Please find attached snapshot for the same.

Thanks

I implemented the fabric locally and I did not see any errors.

My member made purchases and redeemed points but the transaction data is incorrect.
For example:

Points Earned Transactions

timeStamp: undefined
partner: Villanova01
member: 123456
points: 30
transactionName: undefined
transactionID: undefined


timeStamp: undefined
partner: Villanova01
member: 123456
points: 80
transactionName: undefined
transactionID: undefined

and

Points Redeemed Transactions

timeStamp: undefined
partner: Villanova01
member: 123456
points: 50
transactionName: undefined
transactionID: undefined

Appreciate suggestions on how to fix.

VS Code version:- Version: 1.60.2
IBM Blockchain Platform version:- 2.0.4

There is no option for install and instantiate for smart contract at IBM Blockchain platform after packaging. Please see the attached screenshot. Instead of install and instantiate option there is a Deploy smart contract option is there. But deployment failed with error :-

Failed to install on peer Org1 Peer with reason: Error: Could not install smart contact received error: failed with status:500 ::failed to invoke backing implementation of 'InstallChaincode': could not build chaincode: external builder failed: external builder failed to build: external builder 'node' failed: exit status 1 [10/1/2021 12:43:58 PM] [ERROR] Failed to deploy smart contract, Error: Package was not installed. No packageId was returned

I failed to find what's wrong with this, any help?

When I attempt to package the Loyalty contract into a package I get the following error message "Failed to determine workspace language type, supported languages are JavaScript, etc."

I have the contracts folder open in the file explorer, when I press F1 and select IBM Blockchain Platform: Package Open Project" command.

Appreciate any guidance you can provide.

Last error comes from this line in the network.js network.js:304:40

const earnPointsResponse = await contract.submitTransaction('EarnPoints', JSON.stringify(earnPoints));

Anybody a hint what the problem can be or how i can fix this?

The current readme specifies VSCode version 1.26 or greater, but there is an actual requirement of VS Code version 1.35.1 or greater for the IBM Blockchain Platform extension.

If someone picks up an older version of VSCode, they won't be able to install the 1.0.x release of IBM Blockchain Platform
