Nested folders failing to upload in widget
I've set up signed uploads with my upload widget. When I drag a single folder into the uploader, everything works fine. When I drag a nested folder into the uploader, it fails with a lot of 'invalid signature' errors. I swear this was working before, I don't know what changed. I think before (a few days ago?) it was flattening the folders in the Cloudinary console, now the folders are getting added in the console as well.
On the backend I just have
const signature = cloudinary.utils.api_sign_request(
params_to_sign,
process.env.CLOUDINARY_API_SECRET
);

My frontend
cloudinary.applyUploadWidget(
document.getElementById("upload_widget_images"),
{
api_key: XXXXX,
cloudName: XXXXX,
upload_preset: XXXXX,
sources: ["local", "dropbox"],
uploadSignature: generateSignatureWithSocket,
buttonCaption: "Upload assets",
clientAllowedFormats: ["jpg", "jpeg", "png", "mp3", "wav"],
styles: uploaderStyles,
button_class: "uploader-button",
max_files: 20000,
// Downscale the image to 800px width / 500 height
maxImageWidth: 800,
maxImageHeight: 500,
folder: XXXXX, // I've tried with and without this
use_filename: true,
},
(error, result) => {}
);

It seems that when nested or multiple folders are uploaded, the
params_to_signbecomes an array of params to sign, which is probably not helping.

Hi @kannydennedy ,
The upload widget has the `pre-Batch` validation feature where you can analyze and get the folder structure for the source file (see https://cloudinary.com/documentation/upload_widget#pre_batch_validation). And using the information, you can update the `folder` parameter to where your files will be uploaded in your Media Library account through the `prepareUploadParams` event (see https://cloudinary.com/documentation/upload_widget#prepare_upload_parameters). In the same event, the signature can be calculated as well.
