This command fails
az webapp create --resource-group my-rg -n my-app --plan my-plan
with error
ResourceNotFound - The Resource 'Microsoft.Web/sites/my-app' under resource group 'my-rg' was not found.
To me this doesn't make sense. The very purpose of this command is to create the webapp, so obviously it should not expect it to exist before executing the command. Did I miss somthing ?
What I think is happening - the App Service name is already taken and it spits out this silly error, try changing the name to something unique and it will work.
ps. figured it out with a --debug added to the command
