Unauthorized to access Form Recognizer resource

Access denied due to invalid subscription key or wrong API endpoint. Make sure to provide a valid key for an active subscription and use a correct regional API endpoint for your resource.Click Switch Resource to use another Form Recognizer resource.

Identification: Ocp-Apim-Subscription-Key, Edit: XHR request and append ApiKey -> getting 204. So Ocp-Apim-Subscription-Key configuration is missing. No documentation available in terms of configuring Ocp-Apim-Subscription-Key in .env or nginx proxy

    Sheng & Eric, thanks for inputs. I found the exact route cause, technically the request should not be routed(Configure service resource-> Form Recognizer Service endpoint) to cloud endpoint, rather it should be point to custom-template-3 image port(highlighted in yellow)
