Read Labs/Modules/Module-1-Preparing-the-Environment.md and inspect the linked raw Labs/Files/labdeploy.json template. Check where the AKS version is configured and validate the deployment using a supported version and region; done means the Module 1 Deploy button completes without the az aks --get-version error.
