can you please comment on your last fix? I believe smart contract has problems when submitting a transaction. My IBM free Blockchain test network will expire in 5 days...thanks!

Submit "AddResident" transaction.

Hey @ljbennett62 , I am working on adding authentication to the smart contracts to ensure the residents can only send coins that belong to them (as a start). This is in line with the Extending the Code Pattern as described in the ReadMe.md file.

Should have smart contracts and maybe a new .js. file to register multiple users with their wallets by end of week, wanted to know if I should do the PR (when I manage to) to the dev branch, or ask for a new one.

Wanted to run the concept by you

• Admin enrolls new users with id R1, R2 and assigns certificates (instead of user1)

• Transaction to add new resident will be submitted using wallet of R1 at which point the ID is added to the resident's schema (The Resident over here is the equivalent of a participant as used in composer)

let cid = new ClientIdentity(ctx.stub);
var resident = { id: cid.getID() }
await ctx.stub.putState('residents', Buffer.from(JSON.stringify(residents))); 

• At this point we can verify if the id match, else throw an error

• There are a couple of points I want to touch upon, that I will address once I open a complete PR

Do let me know if this is fine by you.

I get this error...
TypeError: window.stitch.buildSigCollectionAuthHeader is not a function

Hi team,
I've followed the steps carefully and diligently, and have gotten it to work perfectly fine until couple weeks back. Now today, when I try to redo everything again (helping out a friend right now), and I instantiate the Smart Contract (.cds file generated from VSCode plugin), I do not get the "Connect to SDK" option in the Blockchain console. I am guessing it has something to do with the recent update to the platform, and there's no backward compatibility.
But if you could help me understand why that would be happening, it'll be really helpful and I would finally stop pulling my hair.
Cheers!

Recently, I had meet problem as error log below from chaincode container after deployed to IBP 2.0.

(node:15) DeprecationWarning: grpc.load: Use the @grpc/proto-loader module with grpc.loadPackageDefinition instead

It would fixed via updated fabric sdk from 1.4.0-beta2 to 1.4.0

Before (won't work)
"fabric-contract-api": "1.4.0-beta2",
"fabric-shim": "1.4.0-beta2"

After (works)
"fabric-contract-api": "1.4.0",
"fabric-shim": "1.4.0"

Could some one take a look at?

Hi,

How can I deploy decentralized energy network app in local host instead of IBM Blockchain Platform?

Thx in advance.

Hello!

Throughout the instantiation of the smart contract, I have faced the following error:

grpc payload is empty: transaction returned with failure: SyntaxError: Unexpected token � in JSON at position 0

Do you have any suggestions where I am wrong?
Cheers!

This are two similar issues: #20, #22

Steps to Reproduce

Following the steps in README:

1. Create a Hyperledger network on IBM cloud
2. Instantiate the sample chaincode
3. Run the application
   • I got the error when running the application as participants

Environment

decentralized-energy-fabric-on-IBP20: commit cdd7411

I followed the lab without any issue until the join a peer to channel when clicking "join channel" I'm getting an "the peer could not join the channel" error without any other information.

Is this a known bug? Am I missing something?

I followed the lab without any issue until the step : Start the client "npm run serve"

I followed the lab without any issue until the Create a peer section but once there, when clicking "Submit" I'm getting an "Unable to create peer" error without any other information.

Is this a known bug? Am I missing something?
