Node.js - download_zip_url callback never fired

I am trying to use the download_zip_url method from a node.js back-end, but I'm seeing no success.

I am using the exact example seen in the docs here:

https://cloudinary.com/documentation/image_upload_api_reference#generate_archive

However, the method callback never gets called - the method never returns an error, nor a result.

I am expecting to get the URL in the result so that I can then pass it to my app's front-end, but maybe there's a fundamental misunderstanding as to how this method works? Otherwise, what might be going wrong?

  @Alex and @PAD SBTELECOMS,

  It turns out that there is no callback for the API call download_zip_url. Our Node SDK code shows no callback here:

  https://github.com/cloudinary/cloudinary_npm/blob/bf7103aac2714002305566d05a53ded4cdcafbca/src/utils.coffee#L848

  Our documentation team has been notified to update the doc.

  I apologize for any inconvenience this has caused.

  Hi @Alex,

  Would you be able to share an example of your download_zip_url call?

  I have added an example here:

  cloudinary.v2.utils.download_zip_url(
      { public_ids: 'dog,cat,lion', resource_type: 'image'},
      function(error,result) {console.log(result) });

  I am looking forward to your update.

  Hi Daniel,

  Thanks for your reply. Here's what I have:

  cloudinary.v2.utils.download_zip_url(
   { public_ids: 'my_folder/my_id'},
   function(error, result){
     if(error){
       console.log('error: ' + error);
     }
     console.log('result: ' + result);
  });

  When I run this, I get nothing on the console. I can confirm the folder and public_id are good - I've tested them on other operations such as create_zip, and they work.

  It really looks to as if the callback doesn't fire at all. What else might it be?

  @Alex,

  I examined our logs, and it appears that the `public_ids` specified was `logos/user_id/date/` which includes a forward slash at the end meaning to add the folder, however, it needs to be a specify the full public_id or a tag. If you would like to share more confidential details, please open a support ticket at https://support.cloudinary.com/hc/en-us/requests/new. You may refer to me on the ticket as well.

  Hi, I also have the same issue, the callback function doesn't get called

  `

  const options = {

  tags:"ready-set-work-facilitators",

  resource_type:"image"

  };

  
  

  cloudinary.v2.utils.download_zip_url(options, (err, result) => {

  console.log("Zipped Response: ", result);

  });

  `

  @Alex and @PAD SBTELECOMS, you are correct. I apologize for that. It looks like the callback is not firing. I am reporting this to our dev team.

  Once I receive an update from them, I will be glad to let you know.

  I have the same issue. How can I return the download_zip_url to the client with node.js?
