Why does the cost function evaluate to NaN in the sensitivity analysis of my Simulink model?

Hello everyone,

I am conducting a sensitivity analysis of a Simulink model of a battery, but the value of the cost function for each sample is NaN (screenshot 1). I checked and the model is able to simulate with the various samples, therefore the NaNs are caused by the warnings (screenshot 2) and errors (screenshots 3 and 4) that appear in the command window once I evaluate the model. The problem is, I don't understand what they are trying to communicate. Do you have any idea on what these errors are saying? Do you have any idea on how to fix the problem?
