+### Fixed
+- Improved REST response parsing for mobile platforms by handling `Content-Type` headers case-insensitively and falling back to JSON body parsing when the payload is JSON-like. This fixes `path` lookups such as `path: 0` failing on Android and iPad for endpoints that return JSON arrays.
