Error in network creation of Hyperledger Fabric network usin AWS blockchain templates for Hyperledger Fabric
-
We are trying to build a blockchain-based solution for the forensic application of vehicular accidents. The accident data of the vehicle is stored to a blockchain network in hyperledger fabric, so that no one can tamper the data, only authenticated authorities who have access to the hyperledger fabric network ledger can access to it which we make use of the channel concept in the hyperledger framework.
So the data from the IoT device (currently we build an app to access data such as accelerometer, gyroscope and GPS from smartphones) is been transferred to the Hyperledger Fabric network. We try to create a Fabric network in the AWS blockchain template for Hyperledger Fabric. Then from this hyperledger fabric, all the organizations who are part of this network such as forensic, insurance, manufacturers etc, are the stakeholders who can access the data in the network via the channel (channels helps to bring abstractions ie each stakeholder will only know what is necessary for them).
So we try to create the blockchain network in AWS using Blockchain template for hyperledger fabric. The template for network creation is actually inside a cloud formation stack, which is a service provided by AWS, so we need to create the stack to create the network. Before creating this stack we need to create a VPC, EC2 instance, IAM roles and policies. So we follow according to the below youtube video to create it.
After completing all the above prerequisite, we need to create the template inside the stack. Inside the stack we need to provide stack with the name of the stakeholders in the network ie, forensic, manufacturers etc.. Name of the VPC, EC2 instance ID, all the prerequisite details we created earlier.
When clicking the create a stack, it takes some time to create it, after some time it shows the stack is getting failed and getting rollback, there will be two stacks one is a nested stack of the parent stack, which contains all the artefacts for the hyperledger fabric network it is one which gets failed first, then the parent stack which contains the link to the EC2 instance.
screenshot of the errorIntegration part ie transferring data and accessing ledger can be done only after this stack creation and network spun up.

We try to find more about the error so far this is what we got from it.
So we run user data commands inside instance via SSH. Then error popped up when we run command for network artefacts.
Any suggestions??

In general, the 8085 is an 8-bit microprocessor that was introduced by the Intel team in 1976 using NMOS technology. The microprocessor has been updated with this processor. The 8085 microprocessor has the following configurations: data bus (8 bits), address bus (16 bits), programme counter (16 bits), stack pointer (16 bits), registers (8 bits), +5V voltage supply, and operates at 3.2 MHz single segment CLK. Microwave ovens, washing machines, and other electronic devices use the 8085 microprocessor. The 8085 microprocessor has the following characteristics:
This microprocessor is an 8-bit device that receives, operates, or outputs 8-bit data in a parallel manner.
The processor has 16-bit and 8-bit address and data lines, so the device has 216 bytes of memory, or 64KB.
This is made up of a single NMOS chip device with 6200 transistors.
There are 246 operational codes and 80 instructions in total.
Because the 8085 microprocessor has 8-bit input/output address lines, it can address up to 28 = 256 input and output ports.
This microprocessor is available in a DIP package of 40 pins
In order to transfer huge information from I/O to memory and from memory to I/O, the processor shares its bus with the DMA controller. -
Hi @Vipin-I-V ,
This seems to be an interesting project.
Please share the development here...
I was thinking of something similar, but not for gaming. Won't it be cool to have the Ctrl, Cmd & Alt keys as pedals? Please share your thoughts & insights.

Hi @mkgrmAbhinand ,
Did your issue resolve?

@mkgrmabhinand Hi, It Looks like you didn't install the NodeJS on your computer, or didn't add the PATH correctly in the environment variables.
Could you confirm that you installed the Node JS in your computer from the .exe or .msi installation files?
If not and if you want to run Node-RED, you need to install recommended NodeJS version 14.x and you can download the version here .
