Hi all,



I have some problems with kinvey angular sdk for upload file.

I can successfully create the file entity in files addon, but when I try to upload the file to the address of _uploadURL(google api address), I get this error:



XMLHttpRequest cannot load https://storage.googleapis.com/419b2229ecfd49c3bedb5040bcafdf97/9d6f1c30-1b…PTYfgeQum5ml9hJ3%2Facv7wMrVZBUqHQUGTPZdREwZL%2BeYEMrKjcNHl9MfeD4AhCSf04%3D. Request header field Authorization is not allowed by Access-Control-Allow-Headers.



I am testing with http:localhost:9000/



My code is exactly like [this](https://gist.github.com/vseventer/3835e6cfc5353259afe8 "this")

And if I run chrome with --disable-web-safe option. Kinvey SDK works well.



How can I solve this problem?



Any help is appreciated.



Thanks

Yes, Exactly the problem. I just deleted some custom header on my $http, and it works well now!

Thanks.
