Hi all
We are setting up the “APP Gallery” on our APEX 23.1 instance. This to make custom-apps available to install.
As the documentation explains a manifest.json must be created and hosted on a webserver over https/http. No issue here, all is working fine.
Update the instance Gallery links to put the custom url to the manifest.json, no issue here.
After opening the APP Gallery I see in the ‘Network sniffer’ of ‘Google Chrome’ that a “CORS”-exception is raised when accessing the custom manifest.json. This exception is described the documentation and a solution is mentioned. However the solution is not 100% clear to me.
Following is mentioned in the doc:
Tip: Because of Cross-Origin Resource Sharing (CORS), the web server must be configured to include the Access-Control-Allow-Origin HTTP header to tell the browser that a certain resource is allowed to load from a given host/domain.
My Qeustion about this “Tip”:
Where do I need to configure this HTTP-header? Is it on the APEX-webserver or on the webserver that provides the url for the custom manifest.json?
Kind Regards
