What does this error mean with "configured for prototyping" that I get during test harness creation for my model in Simulink Test R2022a?

The complete error message reads:

The model 'MyModel' failed to compile. Select 'No' to see error messages from compile. Select 'Yes' to create a harness configured for Prototyping (this can be changed later).

This refers to this documentation paragraph:

https://www.mathworks.com/help/sltest/ug/select-test-harness-properties-for-your-task.html#bvnomrz

"Create without compiling the model"

The Harness Rebuild Options are set as shown below if you click 'Yes':

You need to change the setting later (when the model is compilable again) if you want it to compile during harness rebuild.
