Adding of include search path for JS scripts is not supported by this host application

Hey,

I'm currently writing a CEP extension for Adobe Bridge CC 2022. I ported it over from Premiere since it turned out the feature set I need, was a better fit for Bridge.

Now I've hit a roadblock. 
I can't load my host scripts via the scipts provided in the Premiere sample panel.

When I call csInterface.evalScript()  in my panel for the first time, I get following error:

INFO  Adding of include search path for JS scripts is not supported by this host application

Googling this yields no results. 
The folder structure of my project currently looks like this:

I have a working connection to the KBRG Host, and I could confirm that KBRG_TimecodeCorrection.jsx wasn't loaded. Do i use the wrong folder paths or does this approach just not work in Bridge?

Any help would be greatly appriciated.
