What happened?

When a histogram pointing to a NeXus search term is added to a menu widget of an App, the Nomad GUI crashes.
This is the Menu definition:

                Menu(
                    title="Instrument",
                    items=[
                        MenuItemTerms(
                            quantity="data.ENTRY.INSTRUMENT.name__field#pynxtools.nomad.schema.Root#str",
                            width=12,
                            options=10,
                        ),
                        MenuItemHistogram(
                            x="data.ENTRY.INSTRUMENT.energy_resolution.resolution__field#pynxtools.nomad.schema.Root#float",
                        ),
                    ],
                ),
