Empty eкror "Cannot create FMOD" is thrown when AudioType in request differs from actual file type

To repro:
1. Run server.js from TestServer attached folder. (On this server I store *.mp3 file).
2. Run Project attached.
3. Press Play and click GetAudioClip button. (Here "var www = UnityWebRequestMultimedia.GetAudioClip (url, AudioType.OGGVORBIS);" is called).

Actual result: Empty error appears, in log:
Error: Cannot create FMOD::Sound instance for resource ïç, (Unsupported file or audio format. )

Expected result: Error should explicitly show the error.
