Can I raising an error when a particular log is output?

[jiyeong08]

First of all, I'm sorry for my poor English.
I left the same question in the repository of 'webui-reactor', but I think I can get help here as well.

I'm using webui and reactor via api in python code.
If Reactor does not recognize a face in the source image, can I raise an error in my code?
Such as when console message "ERROR - Age Detection: No face with index = 0 was found", "Gender Detection: No face with index = 0 was found","STATUS - No source face(s) in the provided Index"?

It's about reactor, but I hope I can get some help here because I want to run webui and cause an error when certain logs are output.
