Oh, this is fantastic! For some reason I was under the impression that local mode skipped the cloud infra but still needed the development machine to do the build (and balena build fails here). But balena push to a development device in local mode seems to be working! A bit slow, but maybe still faster than going through the cloud. (We are paying for Balena Cloud.)
Thanks, this helps a lot!
Regarding the reported bug, is it a Balena build issue or blocked on an upstream dependency?
