Dropbox Community ModeratorI can't offer any insight on using Angular or Express, but based on the error output, which cites XMLHttpRequest, it seems like your setup is trying to make an ajax call to /authorize, instead of sending the user there directly in their browser. The /authorize page is a web page the user needs to interact with directly, not indirectly from another page via JavaScript, so CORS shouldn't come in to play. You'll need to look in to how to configure your web framework to redirect the user normally, as opposed to making a XMLHttpRequest. Apologies I don't have any Angular or Express insight to share for that, but perhaps someone else on the forum does.
Hi Greg,
Thanks a lot for your response! Since it seemed to work before (I made some changes to my server), I retracted my changes to my code and now am getting a slightly different version of this error which is as follows. It happens when dropbox tries to redirect to my callback function. It seems like my server refuses to accept the redirect back from dropbox:
XMLHttpRequest cannot load https://www.dropbox.com/oauth2/authorize?client_id=...&response…..&redirect_uri=https%3A%2F%2Flocalhost%3A3443%2Fcallback. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://localhost:3443' is therefore not allowed access.
Any ideas? Does your response from before still apply to this case?
Many thanks for your time.
