How do you serialize a `pulumi.StringPtrOutput` with `pulumi.Sprintf`? I’m getting this: `"serviceAccount:&lt;...&gt;.svc.id.goog[%!s(*string=0x140001425d0)/%!s(*string=0x140006169b0)]"` from:

```pulumi.Sprintf("serviceAccount:%s.svc.id.goog[%v/%v]", config.Require(ctx, "gcp:project"), namespace.Metadata.Name(), ksa.Metadata.Name()),```
The first arg is a string, but the latter two are string pointers.

I suppose that’s normal behavior for `fmt.Printf`: <https://goplay.space/#ncEmglC2dUI>

I suppose I could write an `ApplyT` func that converts it to a string from a string pointer

Just following up, but that’s what I went with:

```// UnwrapString converts a StringPtrOutput to a StringOutput.
//
// If the string is `nil`, an empty string will be returned.
func UnwrapString(sp pulumi.StringPtrOutput) pulumi.StringOutput {
	return sp.ApplyT(func(v *string) string {
		if v == nil {
			return ""
		}
		return *v
	}).(pulumi.StringOutput)
}```
```pulumi.Sprintf("serviceAccount:%s.svc.id.goog[%v/%v]", config.Require(ctx, "gcp:project"), UnwrapString(namespace.Metadata.Name()), UnwrapString(ksa.Metadata.Name()))```
