Deprecated API is not viewable in WSO2 API Manager 4.1.0

There is Pizzashack sample API is deployed in WSO2 APIm 4.1.0

However API state has been moved to Deprecated in sometimes before.

When click on this API to make some changes (delete/moved to some other state etc) , It is loading, not getting any response.

As suggested below, adding xml of the registry artifact of PizzaShackAPI:

<metadata
xmlns="http://www.wso2.org/governance/metadata">

<uritemplate/>

How can we get overview page OR to do some other action on the same API?

Solution

Seems like your artifact is missing some mandatory fields. Can you fill it in with the following information?

Endpoint config:

{"endpoint_type":"http","sandbox_endpoints":{"url":"https:\/\/localhost:9443\/am\/sample\/pizzashack\/v1\/api\/"},"production_endpoints":{"url":"https:\/\/localhost:9443\/am\/sample\/pizzashack\/v1\/api\/"}}

Cors Configurations:

{"corsConfigurationEnabled":false,"accessControlAllowOrigins":["*"],"accessControlAllowCredentials":false,"accessControlAllowHeaders":["authorization","Access-Control-Allow-Origin","Content-Type","SOAPAction","apikey","Internal-Key"],"accessControlAllowMethods":["GET","PUT","POST","DELETE","PATCH","OPTIONS"]}

API Security:
