Access-Control-Allow-Origin
i'm using javascript fetch(url,
{
method: 'GET',
mode: 'cors',
cache: 'no-cache',
credentials: 'same-origin',
headers: myHeaders,
referrer: 'no-referrer', }
Error:-
Access to fetch at 'https://www.dropbox.com/s/v2pca6kq8nsqmso/abb5c48dae55560e4ae7d41af7bfdc50.jpg?raw=1' from origin 'http://localhost:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: 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 see you already posted this on StackOverflow and got a response there. That response is correct, Dropbox doesn't allow CORS requests on www.dropbox.com.
I am facing this issue with file served from dropboxusercontent.com, is this supposed to happen?

query for dreambox Unfortunately, using dropboxusercontent.com is not officially supported, so I can't offer help with that.
What exactly is meant by not "officially supported", is Dropbox supposed to be used only for media content(e.g. images and video) storage but not static content(css JS and other files) because with no access-control-allow-origin all these file will be blocked by browsers ?

query for dreambox Regardless of the file type, substituting in 'dropboxusercontent.com' in Dropbox shared links like this is not something that Dropbox documents and may break without notice, and we can't offer technical support for issues that occur when doing so.

Hm...š¤ Greg, you may need to inform your shared links product manager about that! Just take a look here. š¤·š¤¦ He may have no any idea that it's unsupported! šš¤« Would be nice the different Dropbox departments speak to each others and avoid such a confusions like is something supported or not. š
