Error: command is not compatible with this image

Hi… This seems to be the culprit. My own PG instance has a v0.0.62 there, and the source code surrounding that particular message specifically is checking the ImageVersion:

// Validate image version to ensure it's compatible with this feature.
if machine.ImageVersion() == "" || machine.ImageVersion() == "unknown" {
  return fmt.Errorf("command is not compatible with this image")
}

This glitch seems to crop up occasionally, maybe in connection with lower-level Machine problems. Was it recently migrated, by any chance? (You can check with fly m status, in the INFO column.)

[Also, if you do have Support for the corresponding organization, I think this would qualify, :ring_buoy:.]

Hope this helps a little!

Thanks; yeah, I am in contact with support.

For added context, this particular app is a --fork-from another pg app, so the machine is very recently created. The source pg app has version v0.0.46.

Weirdly, I ran the exact same command I use to create the pg app again, and the new app had a valid version (same 0.0.46). I can only conclude that this is a transient issue.
