@srinivasa78 , just checking... have you tried this(below replacing the external content) in a manual testing tool or a REST client like Postman?

"body": {
      "files": [
        "file:media/test.wav"
      ],
      "metadata": {
           "name": "name",
           "fileName": "test.wav",
          "location": "location",
       }
    }

What does the API server responds with?
