I have no trouble accessing the Backendless API except for sending POST requests to the Files service, for which I get the error: “XMLHttpRequest cannot load https://api.backendless.com/C855FF23-D9F5-874A-FFC4-300F60B6C300/v1/files/9C29640F-D5BF-4E0A-FFB3-5842D6E9E900/5NBQHX/Application%20Form. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https://www.mydomainname.com’ is therefore not allowed access.”
I’m using AngularJS, specifically the Angular-File-Upload library (https://github.com/nervgh/angular-file-upload) via REST. I see there is no CORS header on the file upload response, like there is on the other API calls I make to login and call data etc. I have setup the origins in the Backendless UI.
Any help you could give would be much appreciated.
Below are the headers for the options and post requests:
