Summary

Opening the Settings page threw an unhandled promise rejection every time:

Uncaught (in promise) Error: Unknown error

Root Cause

The three HTTP server IPC handlers are inconsistent in how they return data:

invokeIpcWithResult() in the preload layer expects every handler to return an IpcResult<T> envelope ({ success, data }). When success is absent it's falsy, so the function throws:

if (!result.success) {
  throw new Error(result.error ?? 'Unknown error'); // result.error also undefined → "Unknown error"
}

GeneralSection calls api.httpServer.getStatus() on mount, so the error fired immediately every time Settings opened.

Fix

Wrap the HTTP_SERVER_GET_STATUS return value in the standard IpcResult envelope, matching the other two handlers.

// Before
ipcMain.handle(HTTP_SERVER_GET_STATUS, () => {
  return { running: httpServer.isRunning(), port: httpServer.getPort() };
});

// After
ipcMain.handle(HTTP_SERVER_GET_STATUS, () => {
  return { success: true, data: { running: httpServer.isRunning(), port: httpServer.getPort() } };
});

Files Changed

Test Plan

• Open Settings — no Unknown error in the DevTools console
• HTTP server toggle in Settings still starts/stops correctly
• Server status indicator reflects current state on Settings open
