I'm not sure what's causing that error message, but I'm not sure that
code's exactly what you want.
remove_element() returns the element that's removed - which in this
case will be stringified and inserted into the template.

If you don't want the field printed, then you'll need the CALL directive:

[% txt = form.get_all_element('field1') %]
[% CALL txt.parent.remove_element( txt ) %]
