Cannot change base url of tower host in AWS settings page

,

Hi All,

We did install AWX 18.0 version today on minikube using AWX-operator. The installation was smooth and we were able to get the application up and running. After logging in I tried to change the base url of tower host but it doesnt allow me to save the changes. This is the error message from awx-web container
