Previously, trying to select a missing layer or channel via batchPlay was resulting in exception. It’s not anymore.  
Does anybody know what is the right way now to know that batchPlay actually failed? I don’t see anything in the resulting descriptor.  
I expect following code to fail with exception

```auto
await require("photoshop").action.batchPlay([
        {
          _obj: "select",
          _target: [
            {
              _ref: "channel",
              _name: "Non Existing Channel",
            },
          ],
        }
      ], {synchronousExecution: false,
        modalBehavior: "fail"})

```

Both selecting existing and non-existing channel results in an empty descriptor for some reason.
