Sling model exporter + ReactJS - CORS error

[#1]

Hello.

Could you give me some advice on how to fix the error:

I created a Sling Model with an exporter and I'm trying to get JSON on request from the ReactJS App.

ReactJS app:

I also created a filter for the set headers for CORS:

If I make a request from the browser, I will get JSON but not from ReactApp.

And configuration from AEM:

I use AEM 6.4 version. 

Could you please tell how to solve this problem.

Thanks in advance for any advice.

Have you tried configuring the "Apache Sling Referrer Filter OSGI configuration"?
