I don't know if this an error, but a node file should be created but it's not. a screenshot of the output is attached
Edit: I'm using ibm blockchain platform vscode extension. changed the infrastructure.type from "saas" to "software" while the previous error is gone another one apperead "I'm using the ibm platform extension on vs code. changed the infrastructre.type from "saas" to "software" in the "playbook.yaml" file, that error is gone but a new appeared

Answer 1

The ansible role provides support for 3 options, saas, software and docker.
saas refers to IBM Blockchain platform in the cloud, ie the software as a service offering in IBM Cloud, so you need to have provisioned IBM Blockchain platform on the IBM Cloud for this option.
software refers to IBM Blockchain platform software which you need to purchase from IBM and have it deployed.
docker refers to a local deployment on your machine using docker of the Open Source Hyperledger images it creates a local fabric network on your machine.
I'm guessing that you would want to use the docker option.
