The error message clearly indicated that the fileId is not found. Where did you get the contentUri with the id? Did you read it from the a team and detect the id from the attachments object?

Hello ​@PhongVu Thanks for your response to this.

I just picked the contentURI from the export job that I created. I created an export job that gave me a file with the below content shown on the screenshot
 

I then used the contentURI from the export job to try and retrieve the media object. The media objects are in the folder named Files

Attached is the screenshot of the exported JSON files containing media object details, contained within the files directory
 

This here is sample object I obtained within one of the JSON files. The JSON files contain lists of objects in the format provided below:

 

  {
    "id": "846731247626",
    "creator": {
      "id": "62579284004"
    },
    "chatIds": r
      "923061387266"
    ],
    "creationTime": "2020-03-19T21:58:40.622Z",
    "lastModifiedTime": "2020-07-09T14:51:09.192Z",
    "lastModifiedBy": {
      "id": "62579284004"
    },
    "name": "image.png",
    "size": 78745,
    "contentUri": "https://dl.mvp.ringcentral.com/file/846731247626",
    "deleted": false,
    "type": "File"
  }
]


For a literal example, I am attaching screenshots of the get request I made using the above sample object:

Request 1

Request 2

I hope this is clearer to explain my challenge. Hoping to get a solution to this soon as I have been stuck on this for a while trying to figure out how to build a proper request.



 

In that case, the second screenshot is correct. You don’t add the file name to the end of the contentUri.

Now I am not sure about the error. Can you double check the access token you used in your postman is generated for the same user who exported the team messaging compliance and under the same account?

If you want to try this on Node JS code, install the RC JS SDK and provide your app and user credentials to run the code below.

const RingCentral = require('@ringcentral/sdk').SDK
const fs = require('fs')
const https = require('https');
const url = require('url')

RINGCENTRAL_CLIENTID = ""
RINGCENTRAL_CLIENTSECRET = ""
RINGCENTRAL_SERVER = 'https://platform.ringcentral.com'

RC_JWT_ADMIN =""


const rcsdk = new RingCentral({
  server: RINGCENTRAL_SERVER,
  clientId: RINGCENTRAL_CLIENTID,
  clientSecret: RINGCENTRAL_CLIENTSECRET
})

var platform = rcsdk.platform();

rcsdk.login({ jwt: RC_JWT_ADMIN })


platform.on(platform.events.loginSuccess, async function(e){
    console.log("Login success")
    var contentUri = 'https://dl.mvp.ringcentral.com/file/XXXXXXXXX'
    var u = url.parse(contentUri);
  	let domain = u.host
  	let	path = u.pathname
    let fileName = "test.jpg"
    downloadFile(domain, path, fileName)
});

// DOWNLOAD FILE
async function downloadFile(domain, path, fileName){
  var tokenObj = await platform.auth().data()
  var accessToken = tokenObj.access_token
  download(domain, path, accessToken, fileName, function(msg){
    console.log(msg)
    console.log("Save atttachment to the local machine.")
  })
}


const download = function(domain, path, accessToken, dest, cb) {
    var file = fs.createWriteStream(dest);
    var options = {
          host: domain,
          path: path,
          method: "GET",
          headers: {
            Authorization: `Bearer ${accessToken}`
          }
      }
    const req = https.request(options, res => {
      var chunks =  ];
      res.setEncoding('binary');
      res.on('data', (chunk) => {
        chunks += chunk;
      }).on('end', () => {
      file.write(chunks, 'binary');
      file.on('finish', () => {
        cb("Download successful.")
      });
      res.pipe(file);
    })
  })
  req.on('error', error => {
    console.error(error)
  })
  req.end()
}

Hope this helps.

​@PhongVu  Thanks for this. Let me try this and will let you know the progress
