No target of that name

  ✗ No target named prod in sealup.yml.
    Did you mean production?  sealup deploy production
    Targets in sealup.yml: staging, production.

    More: sealup.dev/e/unknown-target

Exit code: 2. Server changed: no.

What happened

The target named in the command is not under targets: in sealup.yml.

Why

Most often a typo, or a target that lives in another config file.

The fix

Use one of the names the error lists; when one is close, sealup suggests it. To use another config file, point to it with -c <file>.
