Hi @mrmuyi

maybe your Frame "Tester_Sporadic_AtifRequestRHRDA" does not have a compu-method or the compu-method is incomplete.
Canmatrix fails because it does not find "factor" in the scaling of "Tester_Sporadic_AtifRequestRHRDA"

Hi, thanks for your quick reply!
in order to find where is the 0 factor, i print the message by "print(self.name)..."
question 1: I got the result as follow which is not match in VECTOR tool or notebook

then i try to filter out the error by "if self.factor==0 return 0"
and got another error: 'Nonetype' object has no attribute "soureceline"
