Hello Mo :wave:

Doesn't `layers` field expect `List&lt;String&gt;` (with `Output&lt;List&lt;String&gt;&gt;` overload), not `String`?

I wrote this piece of code that compiles (notice *`Output.all`* usage):

```var exampleLayerVersion = new LayerVersion("exampleLayerVersion");

var exampleFunction = new Function("exampleFunction", FunctionArgs.builder()
        .layers(Output.all(exampleLayerVersion.arn()))
        .build());```
You can also use `.applyValue` if you prefer:

`.layers(exampleLayerVersion.arn().applyValue(List::of))`

Let me know if that helps. If not, having a code snippet (with import statements) could help me understand your issue better.

Hello,

Indeed, it does not expect a String directly, it uses `String...` where a single String can be passed.
But to the main point, that does help.  `Output.all(...)` does the trick, thanks!

the online documentation probably needs to be updated, the example does not work
