"Default role required" appears when no valid dubbing role is selected for the chosen target language.
- Go to the Dubbing channel row on the main interface.
- First select your target language (e.g., "English"), then choose a specific role from the Dubbing role dropdown (do not leave it empty or "No").
- If you intend to use voice cloning, ensure the channel supports
clone and your setup (reference audio, API) is complete.
If the error persists, check the logs/ folder and provide the latest log bottom (≈30 lines) for further diagnosis.
