Got below logs in wso2carbon.log

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

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

Answer 1

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:
oauth2,oauth_basic_auth_api_key_mandatory

Answer 2

This is a known issue in APIM 4.1.0. If you create a new version of the API (v1.0.0 and v2.0.0) and during the publishing step of v2.0.0, you have the option to deprecate the v1.0.0 while publishing v2.0.0. There was an error in this flow that corrupts the artifacts of v1.0.0. v1.0.0 status is changed to deprecated, however, you can't open or delete the existing API. This has been fixed by fix.
As a solution, you need to fix the corrupted artifact. Luckily you should have a version that is not corrupted and you can use the fields in the v2.0.0 to fix the corrupted v1.0.0.
Log in to the carbon console.
Access the registry artifacts from "Browse" in the Resources section of the Main tab.
Navigate to /_system/governance/apimgt/applicationdata/provider/<user>/<API_Name>/
Here you can find both versions of the API. Navigate to the latest version and open the api artifact.
Navigate to the corrupted version and open the api artifact.
You should be able to see that some data in the corrupted version is missing and they are populated in the working version. By manually adding these fields, you should be able to get the corrupted version working again.
