thanks a lot for the report! The build is running on a k8s job, so maybe it's still ongoing but the API that the UI is using to poll and check the status somehow failed.
Regarding the second issue it's probably related on how we finalize the values used during the deployment. I guess we store the information at the very end of the build, so that's why those are missing. It could be a bug, I should check on why we decided to have those at the end.
For the buildpacks is it due to the subfolder? Maybe the buildpacks are using the specified one, but still using the root (or a different one) for the node_modules (just guessing).
It will be very helpful for us to have an easy way to reproduce the bugs. If you could file an issue with an example, or give us more info it will be great! 🙂
