How to consume 1 localhost log

Sorry for the inconvenience, I wanted to ask how I can bring 1 record only in the path localhost: 8081 / queryCalls that is, to be able to show in json the first record only

On the server in app.js is this GET route but I do not get an idea in chrome or postman how to consume only the first record
app.get ('/ queryAllCars', (req, res) => {
  network.queryAllCars ()
    .then ((response) => {
        var carsRecord = JSON.parse (response);
        res.send (carsRecord)
      });
})

Failed to enroll admin user "admin": Error: Calling enrollment endpoint failed with error [Error: write EPROTO 4589469120:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:33

Today the blockchain extension got automatically updated and the docker images and everything was updated to the lastest hyperledger fabric and after the update the enrollAdmin no longer works. I keep getting this error

New extension panel after update

gatewayDiscovery

I'm the IBM Blockchain Platform SRE. I tried this sample to interact with IPB v2. I works find and the document of this sample is very detailed.

However, when our customers of IBP try this sample, some of them encounter the "discovery error:access denied" error. After our investigation, it's because they didn't set the gatewayDiscovery properly base on your document.

Instead of 'fabric-client' API, the fabcar sample utilizes the high level 'fabric-network' to interact with smart contracts, which is a new feature in fabric-node-sdk 1.4. Some of the customer were not aware of that. So they choose to ignore it.

My proposal is, could you please document a little bit more about gatewayDiscovery or highlight gatewayDiscovery is required. So the users will not ignore it.

Many thanks.

Revoke User

Should be good to have access to delete users. as well.

Can you please advise why this server is not reachable?
Any other alternatives to that server?

Client GUI is Based on Angular now, not Vue

The README says the web client is based on Vue JS framework but as of 16 days ago(?) it seems the basis for the client was switched to Angular. The documentation needs adjustment. The client is on port 4200 as a result and the start up requires entering npm start, not npm run serve

Getting error while executing registerUser.js(Need help in priority)

I am using the IBM Blockchain platform console to create the network and using the fabcar sample to connect to the network with SDK. The enrollAdmin.js script is successful but the registerUser.js is giving the below error message.

Failed to register user user1: TypeError [ERR_INVALID_ARG_TYPE]: The "options.ca" property must be one of type string, Buffer, TypedArray, or DataView. Received type object.

As per my analysis the issue is with the line.
const secret = await ca.register({ affiliation: '', enrollmentID: userName, role: 'client' }, adminIdentity);

I am not sure how to resolve it,could you please help on this.

everything sound correct, I created the network using IPB 2.0. when I start the server, i am getting "clien.JS: Channel not found for the name mychannel.

I checked the settings of my platform and 'mychannel' is there.
Do you have any Idea? do you more details?
