Ruby on rails: cloudinary gem Cloudinary::Utils.private_download_url

February 22, 2022 02:44 Edited

Our app used to upload any file extension and could download it as attachment with following code.

Cloudinary::Utils.private_download_url(public_id, 'csv', :resource_type => :raw, :expires_at=>FILE_EXPIRE_DURATION, :attachment=>true)

However few days ago errors occurred with certain types of file extensions and could not downloaded (extension like csv, xlsx, doc.. etc.)

Following error occurs when you try to download file with generated URL

{"error":{"message":"Invalid extension in transformation: csv"}}

Is there any solutions to fix it?

Hi,

Thanks for reaching out.

I can think of two reasons why you got this error:

1) We don't support applying transformations on raw files. If you are trying to convert a .doc, or txt file to CSV - you can do that using the 'Aspose' add-on.

2) The extension of the public id you provided wasn't CSV.

Hope this helps, please let me know if you have any further questions.

Best regards,
Tamara

Hi Tamara,

The public_id that I provided is not a real public id its just a example.
I uploaded file with csv extension with this command
```
Cloudinary::Uploader.upload('file.path', public_id: 'public_id', folder: 'bucket', :resource_type => :raw, :type=>'private')
```
and now I just want to download it as it is (csv no transformations or conversion) with this command
```
Cloudinary::Utils.private_download_url(public_id, 'csv', :resource_type => :raw, :expires_at=>FILE_EXPIRE_DURATION, :attachment=>true)
```
however when you try to download that file with generated url it throws following error
```
{"error":{"message":"Invalid extension in transformation: csv"}}
```
It worked like charm before for months but suddenly it stopped working we did not change any codes.

Hi,

Please take a look at this thread. I believe the following should work:
```
Cloudinary::Utils.private_download_url("x.csv", :csv, resource_type: :raw)
```
Please let me know if it does?

Thanks,

Tamara.

Hi,
Solutions on thread does not work for us.
```
url = Cloudinary::Utils.private_download_url(public_id, format, resource_type: :raw)
download = Cloudinary::Downloader.download(url)
```
Also we want to download our files as an attachment (just download file not to view)
```
Cloudinary::Utils.private_download_url("x.csv", :csv, resource_type: :raw)
```
when you generate a image URL with the upper command (that you suggested) and browse to the url it opens on browser tab, we don't want that and when if it is non image file the file name changes to 'download.csv' not the original file name that we uploaded.

The probem we are having is when downloading non image files (csv, xlsx, doc etc..) that generated with following command
```
Cloudinary::Utils.private_download_url(public_id, 'csv', :resource_type => :raw, :expires_at=>FILE_EXPIRE_DURATION, :attachment=>true)
```
WITH ':attachment=>true' option is not working.
It used to work before now it is not working.

(Actual file uploading code
Cloudinary::Uploader.upload("#{file.path}", public_id: identifier, folder: ROOM_FILE_BUCKET, :resource_type => :raw, :type=>'private', :filename_override=> original_filename)
)

Hi,

I did manage to reproduce the issue you are describing here (I got the same error), but the file was downloaded to my computer as expected. I escalated the issue to our SDK team and it's being reviewed.

Do you just get the error or is it not working? is the file downloaded as expected? Is the request sent as expected (Network arguments compared to our documentation)?

I'm asking these questions because the backend code did not change. Since you are not reporting that this happened due to a new version, it sounds like something in the request might be invalid.

Thanks,

Tamara

Hi,

We are still getting the error and file is not being downloaded for extensions like csv, xlsx, doc..etc. However for other extensions such as jpg, png, pdf ..etc(image type of files) everything works normal.

Hi,

Could you please check if the request sent as expected (Network arguments compared to our documentation)?

Thanks,

Yes we are using Ruby on Rails Cloudinary gem methods just as the documentation written. Please check the code that we have written below.

Actual written file uploading code:
```
Cloudinary::Uploader.upload("#{file.path}", public_id: identifier, folder: ROOM_FILE_BUCKET, :resource_type => :raw, :type=>'private', :filename_override=> original_filename)
```
```
:filename_override=> original_filename
```
We are setting filename_override option for downloading file with filename just as uploaded.

For example if you upload test_name.csv then downloaded file will be test_name.csv not as name overridden with download.csv

Actual written file download url generating code:
```
Cloudinary::Utils.private_download_url(public_id, 'csv', :resource_type => :raw, :expires_at=>FILE_EXPIRE_DURATION, :attachment=>true)
```
With attachment: :true option uploaded file will not be displayed on the browser tab but to be downloaded directly.

Just like we before said everything use to work with upper codes and suddenly it stopped working. Maybe there were some updates on API or some code tweaks that made it not to work. (We are using chrome browser)

Now we are still getting the error and file is not being downloaded for extensions like csv, xlsx, doc..etc.
```
{"error":{"message":"Invalid extension in transformation: csv"}}
```
Is there some kind of workaround or maybe code changes that we should do? We need to fix this ASAP.

Hi,

This bug is in the process and will be fixed in the near future. I'll update here as soon as that happens.

For now, you can use the URL as is, for example:

http://res.cloudinary.com/your-cloud-name/raw/upload/fl_attachment/file-name.csv

Or if it's private:

http://res.cloudinary.com/your-cloud-name /raw/private/s--lYYd_haF--/fl_attachment/file-name.csv

Hope this helps

Best,

Tamara
