Why wouldn't 'StrongDataTypingWithSimulink' for 'Stateflow.Chart' classes be recognized as a property?

I receive an error when I execute the following code:
load_system('sflib');
set_param('sflib','Lock','off');
rt = sfroot;
m = rt.find('-isa','Stateflow.Machine','Name','sflib');
chart = m.findDeep('Chart');
chart(1).StrongDataTypingWithSimulink = 1;
The error message is:
Unrecognized property 'StrongDataTypingWithSimulink' for class 'Stateflow.Chart'.
Why wouldn't this be recognized?

Hi Engenuity,
It is my understanding that you are facing an error while trying to access 'StrongDataTypingWithSimulink' for the class 'Stateflow.Chart'. The possible reason for this error is that 'StrongDataTypingWithSimulink' has been removed and cannot be accessed from MATLAB versions 2022a and higher. This is mentioned in the Stateflow 2022a release notes as:
"In R2022a, the chart property Use strong data typing with Simulink I/O has been removed. Data types of input signals to charts and state transition tables must now match the type of the corresponding Stateflow data object. Otherwise, a type mismatch error occurs."
Refer to the 'Functionality being removed or changed' section of R2022a in the following link for more information:
Hope this helps!
