Hello, I tried following the Fly.io Rails Getting Started Guide, and trying a couple of fresh times I got the following error:

Error failed to fetch an image or build from source: error building: executor failed running [/bin/bash -o pipefail -c ${BUILD_COMMAND}]: exit code: 1
Assuming it’s something to do with dev vs. prod gem environments, but not sure what to try next. Wondering what might be off about my following of the guide / local environment if anything.
Something to do with the ARG BUNDLE_WITHOUT=development:test in the Dockerfile?
Possibly related issues making it through the guide: basic rails app fails to deploy - #37 by Tunde
