CORS error when embedding a graph in localhost page (JWT V-proxy)

Hi,
I am trying to embed some graphs from Qlik Sense authenticating through a virtual proxy with JWT which was working perfectly until now. This is my HTML code that embeds the graph:

<html> <script> var xhr = new XMLHttpRequest(); var token = '<jwt token>' xhr.open('GET', 'https://bi.dglserv.com.br/jwt/single/?appid=39119e36-67e8-42bc-b94e-d2d2f7471a39&obj=HKjPDJ&theme=horizon&opt=ctxmenu,currsel'); xhr.onreadystatechange = handler; xhr.responseType = 'blob'; xhr.setRequestHeader('Authorization', 'Bearer ' + token); xhr.setRequestHeader('Access-Control-Allow-Origin', '*'); xhr.send(); function handler() { if (this.readyState === this.DONE) { if (this.status === 200) { // this.response is a Blob, because we set responseType above var data_url = URL.createObjectURL(this.response); document.getElementById('test').src=data_url; } else { console.error('no pdf :('); } } } </script> <body> <iframe id="test" src="" style="border:none;width:100%;height:100%;"></iframe> </body> </html>

And these are the setting from my virtual proxy:

However I am getting a 403 (untrusted http origin header scheme is not allowed) error when loading the page:

Did anybody else have this problem? How did you fix it?

Are you running your local env on http? Please try to switch over https.
