when clicking on an item (enter change view), without activating show facets: there are no errors.

when clicking on an item (enter change view), with show facets activated: argument of type 'NoneType' is not iterable (see attached file with the trace)

By completely removing the change_view function, the error does not occur (even if show facets is activated).
