No response from Server #11

I was able to run a local instance of your iot-perishable-network on my local pc. via a virtual ubuntu machine. I have a raspberry pi, where I am running the node-red flow. I've got everything working till the composer-rest-server part. When I try to run,the node-red flow it errors with the Following error,No response from server on a post request to the setupDemo api. I tried to curl the same request via the Host Pc.I'm trying to record,send and retrieve gpscordinates via the hyperledger blockchain. The node-red code seems to work fine to some extend but not all parts especially the http clients. A good recap to the node-red code would be highly appreciated.Thanks in advance

Hi @project621c - This code example was super fun but Hyperledger Composer was depreciated in early 2019. The Node-RED http request nodes make calls to the Hyperledger Composer REST APIs. If HyperLedger Composer isn't running or available, those parts of the Node-RED flows will fail.

Thanks for the reply. After some thinking around and moving the fabric instance and node-red flow on the same network(ip-range) I could query the blockchain and get a 200 status ok on the inject nodes. I would like to continue with this project but I don't have much experience with javascript. I can code in go. What do you recon I should do as I would like to build an iot-asset-tracker? PS:I can't afford your ibm-blockchain solution right not .

There is another IBM Code pattern that runs Hyperledger Fabric and Node-RED in a kubernetes cluster and demonstrates IoT Asset tracking. You would need upgrade to an IBM Cloud standard account (credit card required). The good news is that there is a free kube cluster (good for 20 days) that you can use to experiment.
