configuration not found

Error message

configuration not found

What it means

Crush's TUI returns this Bubble Tea message when the user toggles the 'think' mode command but the app's config service returns nil (m.com.Config()). Config is a service that should always be loaded by app startup; a nil value means the UI command is running before/after config lifecycle exists.

Solutions

1. Check why config loading failed at startup (bad crushrc / crush.json) and fix the config file
2. Verify m.com is fully initialized before the TUI processes dialog actions
3. Report as a bug if config was valid — nil config in a running TUI is an internal invariant violation

Example fix

// before
cfg := m.com.Config()
if cfg == nil {
	return util.ReportError(errors.New("configuration not found"))()
}
// after
if err := m.com.EnsureConfigLoaded(ctx); err != nil {
	return util.ReportError(err)()
}
cfg := m.com.Config()

if cfg := m.com.Config(); cfg == nil {
	// skip the toggle or surface a warning instead of dispatching
}

func configReady(m *Model) bool { return m.com != nil && m.com.Config() != nil }

if cfg == nil {
	return util.ReportError(fmt.Errorf("toggle thinking: %w", config.ErrNotLoaded))()
}

When it happens

Trigger: Invoking dialog.ActionToggleThinking (the toggle-thinking command dialog entry) while m.com.Config() returns nil — e.g. config failed to load at startup, or the command fires during teardown/shutdown when the config service has been cleared.

Common situations: Corrupt or unreadable crushrc/crush.json that aborted config loading; racing the TUI before app wiring completes; running the command in a test harness that constructed the model without a config service.
