BIM_KEY list error.... is this you pyRevit?

I am not sure that this specific error is related to pyRevit or not. I think its something from the Keynote Manager tool but I cannot confirm that.

I have looked around Google a lot today to find anything that might point me to where it is coming from. Does anyone recognize this error, whether it’s pyRevit or something else?

TIA

This is not pyRevit related.
“BIM_KEY” is nowhere in the pyrevit code base.
Most probably from the SSG extension, it is all over the place in the code
