get api error: Unable to obtain the API list

sometimes openwhisk-deploy-kube get error, but openwhisk system can run very well. I don't quite understand why such an error occurs when the function can be deployed, very confusing and requires a redeployment of the openwhisk system.

Start by reproducing the intermittent “Unable to obtain the API list” error in openwhisk-deploy-kube while the OpenWhisk system remains functional. Use the issue’s screenshot and compare the failing deployment state with a successful one; done means identifying a reliable cause and preventing the need to redeploy the system.
