How to parse this tag from stack file
Copy code
demo:tags:
    Environment: Development
Copy code
type Tags struct {
	Tags map[string]pulumi.String `yaml:"tags"`
}
...
cfg := config.New(ctx, "")
var tags Tags 
if err := cfg.GetObject("tags", &tags); err != nil {
	return err
}
...
...
server, err := NewVMInstance(ctx, name, &VMInstanceArgs{
  Tags:  pulumi.StringMap(tags), // This part is throwing error 
  // cannot convert v.Tags (variable of type map[string]pulumi.String) to pulumi.StringMap
})

The 
Tags
type you're unmarshalling to should just be a plain map[string]string. The rest of the answer is here https://github.com/pulumi/pulumi-azure/issues/460#issuecomment-688840667

Hi @lemon-agent-27707 What should we do to make fmt.Print* work in main.go, or other files. That'll be a huge help for debugging. In the above case I'm pretty sure, I did goofed up something.
