Setting secrets doesn't work when a shell machine is created before app machines

[benbjohnson]

Per @lillianberryfly:

$ fly secrets import <secrets
Secrets are staged for the first deployment

$ fly m run --shell [...]
[...]

$ fly secrets import <.env.production 
[WARNING] Your app doesn't have any Fly Launch machines, so we'll create one now. Learn more at

Error: could not find image to use for deployment; backend error was: current release not found for app X

I wasn't able to reproduce this but what I found out is the shell machine doesn't have any of the app's set secrets.
