app-not-mounted: Micro app not mounted

Cause

A handle's unmount() was called, but when that unmount got its turn the app was not mounted, so there was nothing to unmount:

• The app never mounted: loading, bootstrap, or mount failed.
• The app was already unmounted, and unmount() was called again.

When a failed mount caused it, the error's cause is that mount failure, the same object mountPromise rejected with.

Troubleshooting

1. Check the error's cause. If it is set, investigate that mount failure first; it has usually been reported once already through mountPromise.
2. If cause is empty, look for several places calling unmount() on the same handle, or a second call after the unmount finished.
3. Use getStatus() to confirm which state the app was in when unmount() was called.

Solution

Call unmount() only for an app that is mounting or mounted, and unmount each mount once. Code that already handled the mount failure on mountPromise can ignore an unmount() rejection whose cause is that same mount error.
