Playing audio from streaming assets - how do I stop error being thrown if file isn't there?

Hiya,

I'm playing audio files from the streaming assets folder.

If the file I'm looking for isn't there, I don't want an error to be thrown, but instead I just want to log a message to the console.

I can't work out how to stop an Invalid Operation Exception error being thrown. Does anyone know how to do this?

This is how I'm reading the files:

     public static string GetFileLocation(string relativePath)
     {
         string filename = relativePath + ".wav";
         return "file://" + Path.Combine(Application.streamingAssetsPath, "Audio", filename);
     }
 
     IEnumerator AudioPlayer(string audioPath)
     {
         using (UnityWebRequest uwr = UnityWebRequestMultimedia.GetAudioClip(GetFileLocation(audioPath), AudioType.WAV))
         {
 
             yield return uwr.SendWebRequest();
 
             if(uwr.isHttpError || uwr.isNetworkError)
             {
                 Debug.Log("error");
             }
 
             if (audioSource.clip != null)
             {
                 audioSource.Stop();
                 AudioClip currentClip = audioSource.clip;
                 audioSource.clip = null;
                 currentClip.UnloadAudioData();
                 DestroyImmediate(currentClip, false);
             }
 
             if (uwr != null)
             {
                 audioSource.clip = DownloadHandlerAudioClip.GetContent(uwr);
                 audioSource.Play();
             }
             yield return null;
         }
     }

Thanks, Laurien
