What causes "failed to inject target view: %w" in derailed/k9s?

Simply retry the jump once the UI is idle

failed to inject target view: %w

Error message

failed to inject target view: %w

What it means

The jump rule was fully processed (source fetched, selectors built, target view constructed, namespace switched) and the final step app.inject(v, false) failed. inject pushes the new viewer onto k9s' page stack; failure means the app refused the view — most often because the app is shutting down or the view stack is in an inconsistent state. This is an internal/rare failure, not a config syntax problem.

Solutions

Simply retry the jump once the UI is idle
Avoid triggering jumps during context switches or shutdown
If it reproduces reliably for one rule, capture k9s logs and report — the wrapped error identifies the inject failure

Defensive patterns

Strategy: try-catch

Try / catch

if err := customJump(app, gvr, path, rule); err != nil {
    if errors.Is(err, errViewInjection) || strings.Contains(err.Error(), "failed to inject target view") {
        // transient navigation failure — safe to retry once the UI settles
        app.Flash().Errf("jump failed, retry: %v", err)
    }
}

Prevention

Trigger jumps one at a time; do not stack navigations while a jump is in flight
Avoid jumping during context switches or quit
Capture k9s logs when it reproduces — the wrapped error names the inject failure

When it happens

Trigger: Triggering a custom jump at the same moment the app is quitting or another navigation/inject is in flight; race between queued UI updates and view injection.

Common situations: Fast keypresses queuing a jump while the previous navigation runs; jumping right after :quit or context switch; very rare timing-dependent states in custom jump handling.
