No active terminal pane to focus.

Error message

No active terminal pane to focus.

What it means

focusActiveTerminal resolves the active terminal pane by walking store state → activeTabId → window.__paneManagers.get(tabId) → getActivePane/getPanes, and throws if no pane is found before calling terminal.focus(). It runs inside runWithTimeout so a frozen evaluate surfaces as a timeout, while a missing pane surfaces as this error.

Solutions

1. Ensure setupTerminal completed and the 'active terminal PTY binding' condition passed before focusing.
2. Confirm state.activeTabType === 'terminal' and state.activeTabId is set at the moment of focus.
3. Re-check window.__paneManagers has an entry for the active tab id.

const hasActivePane = () => page.evaluate(() => {
  const state = window.__store?.getState?.()
  const tabId = state?.activeTabType === 'terminal' ? state.activeTabId : null
  const manager = tabId ? window.__paneManagers?.get(tabId) : null
  return Boolean(manager?.getActivePane?.() ?? manager?.getPanes?.()[0])
})
if (!await hasActivePane()) throw new Error('cannot focus: no active terminal pane')

When it happens

Trigger: The active tab is not a terminal, the tab id resolves to no pane manager, or the pane manager has no panes (terminal not yet mounted / torn down).

Common situations: Called before the terminal pane was mounted (PTY binding incomplete); activeTabType flipped away from 'terminal'; pane manager map missing the tab id.
