CORs error on forced download links

I am trying to request an obj file from a publicly shared link.

The link is "https://www.dropbox.com/scl/fi/xh3vmyt9d74cl5cbhqgpm/Antigen.obj?rlkey=b4zcediso03wiuc96w3agm6rg&dl=1"

Which successfully downloads if you go directly to it, but when I try to load it in my site, I get this error:

`Access to fetch at 'https://www.dropbox.com/scl/fi/xh3vmyt9d74cl5cbhqgpm/Antigen.obj?rlkey=b4zcediso03wiuc96w3agm6rg&dl=1' from origin 'https://simularium.allencell.org' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.`

I am using the THREE.js OBJLoader

This workflow used to work for us. Has something changed?

yes so what ended up working for me was:

`url = url.replace("www.dropbox.com", "dl.dropboxusercontent.com");`

with a url that has `dl=1` and a `rlkey` as parameters.

thanks!

Hi @meganrm, thanks for bringing this to our attention.

Have you been using the new style of shared links for this method, or the old style?

This will help me to assist further!

It's a very recently generated link, so I assume the "new style", I also put the link in my message so you should be able to see the format.

Could you try the suggestions in this thread to see if they help by changing the URL of the file?

We're glad to hear it's sorted now and thanks for keeping us in the loop too @meganrm

See you around the Community and take care!

Thank you! It said in that post about the `dl.` links: "These are link transformations from the early days of Dropbox. While we don't "officially" list these anymore in our Help Center, we are continuing to support them for now. "

Are there plans to address the CORS issue with the standard share links so that using the `dl.dropboxusercontent.com` will no longer be necessary?

Thanks
