Error while setting context after cdk deploy

[sarekoubeYohane]

Greetings,
While using command to set context from CdkStackALBEksBg stack's output I get the error as
"W0525 09:45:28.801741 26717 loader.go:221] Config not found: /etc/kubernetes/admin.conf
The connection to the server localhost:8080 was refused - did you specify the right host or port?"

Any thoughts will be helpful,
Thanks.
