Incompatibility with WSO2 AM 4.1.0 for API creation

[MioOgbeni]

Description:
Im using WSO2 APIM 4.1.0 deployed in K8S cluster and I want to use k8s-api-operator for creation of WSO2 APIs from K8S CRDs. When I configured all needed credentials and endpoint and want to let k8s-api-operator to create API in WSO2 APIM . Then I found out that k8s-api-operator using hard-coded publisher endpoint [here] API v2 for listing APIs but in WSO2 APIM 4.1.0 is only avilable publisher API v3.

Affected Product Version:
2.0.3

OS, DB, other environment details and versions:
WSO2 APIM 4.1.0 installed from single instance helm chart here
WSO2 k8s-api-operator 2.0.3 installed form manifest here
Deployed to K8S 1.25.5

Steps to reproduce:

• Deploy APIM 4.1.0
• Deploy k8s-api-operator 2.0.3
• Configure valid in-cluster apimKeymanagerEndpoint, apimPublisherEndpoint, apimTokenEndpoint and WSO2 APIM secrets for k8s-api-operator
• Deploy swagger openApi definition as CM into cluster for desired application.
• Deploy API resource with spec swaggerConfigMapName
• In k8s-api-operator logs will be displayed this

Can be also reproduced from Postman

• GET request to http://WSO2_APIM_HOST:WSO2_APIM_PORT/api/am/publisher/v2/apis will end with status code 404
• GET request to http://WSO2_APIM_HOST:WSO2_APIM_PORT/api/am/publisher/v3/apis will end with status code 200 and return list of APIs

For now I will downgrade my WSO2 APIM to version 4.0.0 as quick fix.
