Hi Pierre,
Could you help me understand how you're using the NodeJS SDK? Are you running it inside a container and trying to read secrets managed by the Connect Operator?
The Operator is simply a way to bring your 1Password secrets into your Kubernetes cluster. The Operator will inject secrets into your Kubernetes pods at run time and give the containers access to the secrets via environment variables.
This means you aren't going to be able to directly hit http://localhost:8080/v1/vaults
because you don't have any containers exposing that endpoint.
