Derivative of state '1' in block 'partial_s​hading_by_​PSO/PV Array/Diode Rsh/BAL/Transfer Fcn' at time 0.18545801959987063 is not finite

I want answer to this error message

An error occurred while running the simulation and the simulation was terminated

Caused by:

Derivative of state '1' in block 'partial_shading_by_PSO/PV Array/Diode Rsh/BAL/Transfer Fcn' at time 0.18545801959987063 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

Hello, I'm having this error.

How did you solve this ?

I have this error too, any solution?
