Hi @jakekgrog, can you describe the issue in more detail? I ran a few tests and the enclaves seem to start just fine without --attach-console flag in either debug or production mode on release 1.2.0.

There is no need for Optional there, as this doesn't reflect in either the way the CLI interprets the flags or the way that flag is used later on.
