Not available yet

  ✗ --mirror is not available yet in this version.
    sealup stops rather than ignore it.

    More: sealup.dev/e/not-available-yet

Exit code: 2. Server changed: no.

What happened

A key or a value names a feature that this version of sealup does not have yet.

Why

Ignoring it could do something you did not ask for: a deploy with a safety net turned off. No key or value of this version stops with this error: it is kept for the features of later versions.

The fix

Use what this version offers: an sftp:// or ssh:// server with a password or a private key, or an ftps:// or ftp:// server with a password. Or remove the value, and run the command again.
