Hello.
We successfully send via Postman POST-type message 'ping' 'hi' to initiator FSC-node and get Ok response from responder FSC-node (in the same way that it happens in ping-pong test-case).

But we get problems when we get try to communicate with our HLF network in the same way as it happened in iou test-case.

Can you give few tips about what we need to do to get communication between FSC-node and HLF-node ?

Here I provide error that we get now when we try to run FSC-node:

exit status 2

And here what we try do :
a) we register identity for FSC-node of type 'client' in our's HLF CA and enroll it
b) after that we add right path to all this ^ certificates in core.yaml that use FSC-node and describe our simple HLF network
c) we install chaincode that used in iou test-case to our HLF network

Our core.yaml :

@andrii482 , please, use this commit 0a9560bb92a5575783b80183c9385817edf7f366. It should give us back a better error message. Thanks again for your support to improve FSC :)

Hi @andrii482,

Please, could you post the entire stack that you get? I need to identify the function that triggers the panic.

Thanks for your feedback :)

I've just noticed that you are using an old commit of FSC. Please, can you try again using the latest commit c50b01136433bf74e9daee6d77441b353c0b5409? Thanks :)

We run git pull , and try the same steps, but still get the exactly same error

Aha, found the problem. It looks like there is no Fabric network defined and the issue is related to your configuration.
You have:

fabric:
enabled: true
default:
  default: true
  BCCSP:

but it should be:

fabric:
  enabled: true
  default:
    default: true
    BCCSP:

Everything shifted by two spaces.

Now, the smart client should definitely fail more gracefully if no Fabric network configuration is found.

Please, let me know if this interpretation is correct and sorry for the late reply :(

We uses correct-formatting core.yaml but github's markdown corrupt yaml formating :(
(so I put core.yaml in pastebin.com and update main topic with its link )

core.yaml :

Indeed, thanks for the clarification :)

Actually, I'm not sure. Is there a way you can send me the entire package with the keys, configuration files, and so on? I can then test it locally.

how do you execute the FSC node? Do you use the node executable?

Not really get what you mean here:

Do you use the node executable?

The simplest way that we use to run fsc-node is:

git clone https://github.com/hyperledger-labs/fabric-smart-client.git

cd fabric-smart-client/cmd/node

cp /home/user/core.yaml .

go run -v main.go node start

When you run the node this way, the fabric sdk is not installed and the error you report cannot manifest itself.
I'm still struggling reproducing it.
