LNG-160 Nullable value becomes nil in a nested object literal

aqua Main

export someFunc

data Nested:
    child: i64

data Res:
    nested: ?Nested

func res() -> Res:
    <- Res(
        nested=?[Nested(
            child=3
        )]
    )

func someFunc() -> Nested:
    r <- res()
    <- r.nested!

fluence run -f 'someFunc()'
{
  error_code: 10007,
  instruction: 'call %init_peer_id% ("callbackSrv" "response") [Res_obj_flat.$.[0]] ',
  message: "value '[]' does not contain element for idx = '0'",
  peer_id: '12D3KooWExkrWuoJNsJXj9V9pdtAhfjuKdVnC9HCzoxVLT1mhuft'
}

Expected:

fluence run -f 'someFunc()'
{
  child: 3
}
