I am trying to convert a Word doc into a Google doc using the API via nodejs. The word docs are already in a folder and I just want to convert them into google docs. I am using v3.
The v3 docs say that in order to convert a file using copy you need to replace the convert parameter with the mimeType in the resource body.
I can't work out how to do that?
function listFiles(auth) {
  const drive = google.drive({version: 'v3', auth});
  drive.files.list({
    q: "mimeType = 'application/msword'",
    pageSize: 100,
    fields: 'nextPageToken, files(id, name)',
  }, (err, res) => {
    if (err) return console.log('The API returned an error: ' + err);
    const files = res.data.files;
    if (files.length) {
      console.log('Files:');
      files.map((file) => {
        console.log(`${file.name} (${file.id})`);
        drive.files.copy({
          fileId: file.id,
          'name' : 'Updated File Name',
          'mimeType' : 'application/vnd.google-apps.document'
        })
      });
    } else {
      console.log('No files found.');
    }
  });
}
Not sure that I am quite understanding how to reference the resource body. Would be grateful for a steer?
