You're using auto_fieldset - so get_elements() will only return the
top-level fieldset - nothing else.

You're calling get_elements - note the "s" on the end - that would
return an arrayref, which isn't what you want.

If you're wanting a field - which you do - then forget all about
get_element(s) / get_all_element(s) - just use either get_field() or
get_fields()

get_field() returns a single field object
get_fields() returns an arrayref of field objects
