MOOC-Grader crashes on loading an exercise model solution

[markkuriekkinen]

grader.cs crashes when loading this exercise model solution:

https://plus.cs.aalto.fi/tietotekniikka-sovelluksissa/2022/python1/python-harjoitukset-1/python1_python-harjoitukset-1_repl/info/model/

Is there a mistake in the course configuration or is the course build producing invalid config? The ValueError is suspicious since valid data should not have "2." (NB. period) in an integer field.

File "/mooc-grader/./access/types/forms.py", line 467, in compare_values
return int(val) == int(cmp)
ValueError: invalid literal for int() with base 10: '2.'

From grader.cs log:
