Tutor is no longer working

Tutor is no longer working.

The example from the Basthon gallery demonstrates this well: here

The indicated error is as follows:

Error: Uncaught PythonError: Traceback (most recent call last):
File "/lib/python3.11/site-packages/tutor/__init__.py", line 78, in _iframe_resize
type = data.type
^^^^^^^^^
AttributeError: type

For your information, it no longer works in the notebook either.
