  • I'm getting an error when deploying that the bin/webserver file doesn't exist when trying to deploy my Lucky app. Any advice on what could be going on?

    Yes! Jumpstart, the template app I use for LuckyCasts, currently uses a `webserver` target in `shard.yml` for the built binary, while default Lucky apps were changed to use `app` as the built binary. Make sure that the relevant references to `bin/webserver` are changed to `bin/app` in your Dockerfile, or change the target in your `shard.yml` from `app` to `webserver`!
