Missing public ids error when using download_zip_url with raw files

Hello all,

I generate a download url using download_zip_url like this:

const zip = await cloudinary.utils.download_zip_url(

            { public_ids: ["rdhkeoccu8on9ahn0jk1"], 

              resource_type: 'raw',

              use_original_filename: true});

And when I open the response link to download the zip I get:

{"error":{"message":"Missing public_ids: rdhkeoccu8on9ahn0jk1"}}

But that ID is not missing since I can find the file in the Media Library.

Is a .3DL file uploaded using the REST (With the raw paremeter).

Thank you in advance,

Jacin.

  Hi Jacin,

  Yes, the .3DL file was uploaded as a raw file. Hence, the file type should be included in the public id.

  Could you please try: 

  public_ids: ["rdhkeoccu8on9ahn0jk1.3DL"]

  Please let me know how it goes.

  Hi Everyone,

  I have a very similar problerm (same error) when trying to generate a download URL for some audio files :
  The assets are wav files and residing in different folders/subfolders.
  
  The returned URL never works, with the most common error being :

  {"error":{"message":"Missing public_ids: share/librairie/chill/Emile_-_Tavel_ppx4a1.wav,share/librairie/chill/Charles_-_Pure_rentwm.wav,share/librairie/atmospheric/Francois_-_Fragance_vsd1xl.wav"}}

  
  This error correspond to this log where i list the public_ids and returned URL :

  
  Generate Zip download URL for share/librairie/chill/Emile_-_Tavel_ppx4a1.wav,share/librairie/chill/Charles_-_Pure_rentwm.wav,share/librairie/atmospheric/Francois_-_Fragance_vsd1xl.wav : 
  https://api.cloudinary.com/v1_1/x-track/video/generate_archive?mode=download&public_ids%5B%5D=share%2Flibrairie%2Fchill%2FEmile_-_Tavel_ppx4a1.wav%2Cshare%2Flibrairie%2Fchill%2FCharles_-_Pure_rentwm.wav%2Cshare%2Flibrairie%2Fatmospheric%2FFrancois_-_Fragance_vsd1xl.wav&target_format=zip&timestamp=1623855345&use_original_filename=1&signature=dd2590506ca6c624041d4f05652419a79741cd8d&api_key=225998376837194 

   

  My source code to retrieve the download URL is this one :

   

  /**
  * Return a calculated link to download a zip archive
  * containing the selected assets
  * @param{Array<String>}public_ids
  * @param{String}format to convert each asset
  * @returns{String}
  */
  export const getZipDownloadUrl = (public_ids, format = "wav") => {
   try {
    // Add the request format to the end of the public_id
    public_ids = public_ids.map((id) =>`${id}.${format}`).join(",");
    const downloadUrl = cloudinary.utils.download_zip_url({
     public_ids,
     resource_type:"video",
     use_original_filename:true
    });
  
    console.log(`Generate Zip download URL for ${public_ids} : ${downloadUrl}`);
    return downloadUrl;
   } catch (err) {
    console.error(err);
    throw new ApiError(500, err.message);
   }
  };

  With the great Cloudinary support, i was able to make my piece of code working, so here is the solution :

  • Audio files must not add the format to the public_id but instead keep the `resource_type: "video"`
  • To convert this audio files to other format, you must use the `transformation` parameter.

  With all that said, here is the working snippet :

  /**
  * Return a calculated link to download a zip archive
  * containing the selected assets
  * @param{Array<String>}public_ids
  * @param{String}format to convert each asset
  * @returns{String}
  */
  export const getZipDownloadUrl = (public_ids, format = "wav") => {
  try {
    return cloudinary.utils.download_zip_url({
      public_ids,
      resource_type:"video",
      use_original_filename:true,
      target_public_id:`download-${newDate().toISOString().substr(0, 19).replace(/[^0-9]/g, "-")}`,
      transformations:`f_${format}`
    });
  } catch (err) {
    console.error(err);
    throw new ApiError(500, err.message);
  }
  };
