Unable to Initiate API Calls to Backend Services

[AhmedYoussefPro]

Hello,

I’m trying to make API calls to communicate with a backend service. However, I always get an error saying that the request is blocked due to CORS policy as the origin of the request is null.

Is there any solution to this issue from the custom visual’s side? As I can’t modify the backend service to allow null origin due to the security risks.

Hello @AhmedYoussefPro

Did you update "privileges" in your capabilities.json accordingly?

@AleksSavelev Yes, I'm setting my privileges webAccess, but I think this is to allow the visual to make external calls to these parameters(domains) while this doesn't resolve the issue of the request origin. The request Origin still comes out with null and once received by a backend service it rejects the request unless you allow null origin in the backend service which is not secure.
