BOX2_NGW6AVvOUtjYOrB4zyHVQw.pngHi Team,

I have added the origin from where I am passing request to box i.e "https://contentintelligence.lightning.force.com" in the Allowed Origin but still I am getting "Access to XMLHttpRequest at 'https://upload.box.com/api/2.0/files/content' from origin 'https://contentintelligence.lightning.force.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."

I have been facing this issue for many days. Is there anything else needs to done in this?

Thanks

    Hi Nidhi,

    That error sometimes also shows up if there is an error with the authentication.

    For example, it happens to me frequently when I'm using a developer token, which is valid for 60 minutes, and I don't realize it has expired.

    Let us know if this helps.

    Cheers
