* fix: Align Read Only badge to right in Prompts.svelte
- Title and command stay on left
- Badge pushed to right by justify-between
* fix: Use PromptAccessResponse in get_prompt_by_command endpoint
fix: Use PromptAccessResponse in get_prompt_by_command endpoint
- Return PromptAccessResponse Pydantic model instead of raw dict
- Properly type the response with response_model
Add optional chaining to file.url.startsWith() calls to safely handle cases where file.url is undefined, preventing 'can't access property startsWith' TypeError in user messages with file attachments.
Add null check before calling .map() on the API response in getChatList(). When the fetch fails silently or returns null, the function now gracefully returns an empty array instead of crashing with 'Cannot read property map of null'.
Use optional chaining and nullish coalescing when accessing res.OPENAI_API_BASE_URLS and res.OPENAI_API_KEYS. Returns empty array instead of crashing with 'Cannot read property of null'.
Add null check after Chats.get_chat_by_id() in both admin and user code paths. When chat doesn't exist, now raises HTTP 404 instead of crashing with AttributeError when accessing chat.meta.
Add null check in list comprehension before accessing session['id']. When a session_id exists in the room but has been removed from SESSION_POOL, the function now skips it instead of crashing with TypeError.
Add null check after db.get(Chat, chat_id) before accessing chat.share_id. Returns None instead of crashing with AttributeError when chat doesn't exist.
Change 'return Exception(...)' to 'raise Exception(...)' in chat_completed() and chat_action() functions. Returning an exception object instead of raising it causes errors to be silently swallowed, breaking error propagation.
Add null check after Files.get_file_by_id() before accessing file.hash. Raises HTTP 404 instead of crashing with AttributeError when file doesn't exist.
Add null checks for ui settings in update_user_settings_by_session_user() and for user in get_notes(). Prevents AttributeError when ui dict is None or when note's user has been deleted.
Fix implicit None returns in get_model_by_id, get_knowledge_by_id, get_tools_by_id, and get_prompt_by_command. Now properly returns 401 for access denied and 404 for not found instead of silently returning None.
