Astronomer+Airflow cannot create pod

The problem is that I am able to run an pod with kubectl but not with kubernetesPodOperator
It looks like the airflow instance isn’t able to interrogate the local minikube cluster (single node).

OS: Ubuntu-20.04
Docker version: 20.10.5
kubectl version: v1.20.5 - linux/amd64
kubectl cluster-info:

   Kubernetes control plane is running at https://192.168.49.2:8443
   KubeDNS is running at https://192.168.49.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
curl -sSL https://install.astronomer.io | sudo bash

Notice: All the installations are local.

task-1 = KubernetesPodOperator(
        namespace='default',
