error "non-concrete value struct" when trying to look on cue struct

[ying-jeanne]

the cue version 0.3.2

When the inputdef.IncompleteKind() is cue.StructKind, i would like to loop on all fields of inputdef by using function iter, err := inputdef.Fields(cue.Optional(true), cue.ResolveReferences(true), cue.Concrete(false)).

Then I got an error panels.268435455: non-concrete value struct, knowing that i would like to loop on element not necessarily concrete. What potentially is wrong here?

Please can you share a repro of what you are seeing here?
