 **Root Cause:** The `AniWorld.ApiClient.request()` function returns a native `Response` object from the Fetch API, not the parsed JSON data. The code was attempting to access properties like `response.message` and `response.content` directly without first calling `response.json()` to parse the response body.
 
 **Solution:** Updated all NFO-related API calls in the JavaScript modules to:
+
 1. Check if response exists (`if (!response)`)
 2. Parse the JSON response (`const data = await response.json()`)
 3. Access properties on the parsed data object (`data.message`, `data.content`, etc.)
 
 **Files Modified:**
+
 - [src/server/web/static/js/index/nfo-manager.js](../src/server/web/static/js/index/nfo-manager.js) - Fixed `createNFO()`, `refreshNFO()`, `viewNFO()`, `getSeriesWithoutNFO()`
 - [src/server/web/static/js/index/nfo-config.js](../src/server/web/static/js/index/nfo-config.js) - Fixed `load()`, `testTMDBConnection()`
 
 **Verification:**
+
 - NFO creation now works correctly from the web UI
 - Error messages are properly displayed with details from the API
 - All NFO operations (create, refresh, view) function as expected
