[BUG] Ghost Slider Function Erroring Out (Potentially PyMaya issue)

[HaydenJSmith]

🐞 Bug Report

Description

When trying to build my facial rig in 5.0.6, the post script errors out when trying to create a ghost slider.
This is the script setup, based off of Miquel's data centric facial rigging tutorials.

Steps to Reproduce

1. Create a NURBs surface for sliding on
2. Create ghost controls using the post script functionality
3. Feed the sliding surface and ghost control into the ghostSlider script

Expected Behavior

Link ghost controls to sliding surface to move over the surface, and continue with future post steps

Actual Behavior

Errors out during post step and prevents rest of building

Maya Version

• Maya Version: 2025
• OS: Windows 10

mGear Version

Additional Context

The brow module is "chain_IK_spline_variable_FK_01"

Ran a quick code test in Maya, using PyMel and PyMaya to run both codes and these were the two results I got.
