How to make Qlik Sense Enterprise re-evaluate descriptions?

[interncat99]

So with the help of QSEA library and my own python code I was able to change all descriptions and labels of my master items. The purpose is to have my python code change master item description to =$(vMIDesc(MI.name_from_MI_table)) expression and then, when the script loads the excel file with descriptions of all items, Qlik should evaluate that expression to the description written in excel file. This works as intended with labels, however with descriptions, I have to edit the master item (front end) and then save to get the actual description instead of the expression. I am using SetProperties method through the Engine API.

My question is where could be the problem here? And if the answer is not obvious, is there a way to access internal operation (engine API?) logs to see what happens exactly when I edit-save the master item so I could try to recreate it with code?

Also let me know if this is the wrong board

changing 

"qDim"[descriptionExpression"]["qStringExpression"]["qExpr"] instead of (or maybe together with) qMetaDef"["description"] did it.
