CPAC error when its running

Hi everyone,
I try to perform CPAC for a subject on an intel chip computer and meet below error on nuisance processing stage. I changed our T1 and functional images with another online dataset and it worked fine. It seems that the error relates to the specification of my images but I don’t know which one, I can not understand the source of error and do not find any solution for it.
Can anybody help me?

What does the log say?
