"path-collection" is empty when getting a file resourse using "box-node-sdk"

We are building an Integration in the box cloud:
1. Application Type: Custom App
2. Authentication Type: OAuth 2.0
3. Context Menu items are added using “Web Integration”

The Web Integration (Context Menu) Configuration is:

1. Supports all file extensions
2. Integration Type is “Files”

We are using BOX-NODE-SDK, to get the file details from the received fileId.

On click of the web-integration, we received the authCode and fileIdin the API.,
Using the AuthCode, we successfully fetched the AccessToken.

const sdk = new BoxSDK({
        clientID: BOX_INTEGRATION_CLIENT_ID,
        clientSecret: BOX_INTEGRATION_CLIENT_SECRET,
});

sdk.getTokensAuthorizationCodeGrant(authCode, null, function (err, tokenInfo) {
  const boxClient = sdk.getPersistentClient(tokenInfo);

  boxClient.files.get(fileId).then((file: any) => {
        logger.info(file);
  })
}

The above code sample returns the file details, but the path-collection is missing in the response.

Under the path-collection object, the entries array is empty and total_count is 0.

{
    etag: "1"
    extension: "txt"
    file_version: {
       id: "***"
       sha1: "***"
       type: "file_version"
    }
    id: "***"
    lock: null
    name: "sample.txt"
    path_collection: {
        entries: [],
        total_count: 0
    }
    size: 7
    type: "file"
    version_number: "2"
}

But, as per the below image - the file is nested under multiple folders.
Any Idea what I am missing here?
