I see the problem, but not sure what cause that. It is because the enable checkbox is unable to display, so causing a null exception.

@jjw24 would you like to take a look on this? I am currently quite busy.

sorry for the late reply. I will look into this if you havent started yet @taooceros

Ok it’s a serious bug because the File Content Search doesn’t contain option to enable or disable, so the NPE is reproducible regardless which actionkeyword is going to be changed.
