# 3839 Fixed handling of None for logic.kernel_module

[rozyczko]

Description

Batch fitting is throwing a (harmless) error. This doesn't look nice.
The bug occurred because self.logic.kernel_module can be None during batch fitting, which caused an AttributeError when updateKernelWithResults tried to call setParam() on it.

Fixes #3839

How Has This Been Tested?

Local Win10 build
