Substance Painter Python issue common_params['HipolyMesh'] File not found error

Substance Painter 2023 Steam Edition

Windows 10

Currently trying to automate part of my Baking, and i've been trying to add a High Defintion mesh within the Mesh map using python BakingParameters.set({common_params['HipolyMesh'] : "C:/Users/User_Name/User_File/cowTest/Cow_HP.fbx"}), however it keeps throwing a "File does not Exist Error". However when I manually select the file it seems to work properly. I was wondering if it was a bug, I was missing a step, or that it should be done another way. Any help would be greatly apperciated Thank you.
