Hey @aplio! 👋 I'm here to help you with bug fixes, answer your questions, and guide you on becoming a contributor. Let's work together to resolve the issue you're facing!

To address the issue of the language field being clearable in the /app/${appid}/overview section and causing errors when saving in Dify version 0.15.3, you should ensure that the default_language is correctly set and maintained in the component's state. The useEffect hook is used to initialize the language state with default_language from appInfo.site. Make sure this state is not unintentionally reset or cleared elsewhere in the component.

Here's the relevant part of the code that handles the language setting:

const [language, setLanguage] = useState(default_language);

useEffect(() => {
  setLanguage(default_language);
}, [appInfo]);

Ensure that the setLanguage function is only called with valid language values and that the default_language is correctly passed and updated in the appInfo object. If the language is being cleared, check for any logic that might be resetting the language state or the appInfo object [1].
