I used document and configuration from: https://buildpacks.io/docs/tools/piper/
I have added Jenkins to docker group - which was the first error I encountered:
info cnbBuild - build settings information successfully created with '{"cnbBuild":[{"dockerImage":"paketobuildpacks/builder:base"},{"dockerImage":"paketobuildpacks/builder:base"},{"dockerImage":"paketobuildpacks/builder:base"},{"dockerImage":"paketobuildpacks/builder:base"},{"dockerImage":"paketobuildpacks/builder:base"}]}

What could I have missed? I am trying it on my virtual machine Ubuntu 22.
