Why does RC return 404 when trying to access recording?

How did you download the content? Can you share some code snippet? Here is some example code using the RingCentral Node JS SDK

async function download_call_recording(){
    console.log("===== download_call_recording ======")
    try{
      const resp = await rcsdk.get("https://media.ringcentral.com/restapi/v1.0/account/1780090xx/recording/89983750xx/content")
      var buf = await resp.buffer();
      fs.writeFile("new_recording.mp3", buf, function(){
        console.log("Done")
      })
    }catch (e){
      console.log(e.message)
    }
}

We try to download using Java client, but even curl is failing, can you check if the resource actually exists? What is the status of the resource?
