Blocking of RTDE sendCustomScript at UR3e polyscope 5.15.2

I am user of UR3e and run Robot Arm using RTDE python interface.
When I call sendCustomScript(“set_tool_voltage(24)”), the call was not returned.
But the 24V applied at the robot tool.
I found similar questions about this issue. But nobody answered.

Why RTDE does not return for sendCustomScript?

I come to know the “set_tool_voltage” method is not valid at RTDEControlInterface.
using script is the last method to control tool connector voltage.

I also tried ROS2 interface to use URCap rs485-1.0.urcap.
It does not applied to polyscope 5.15.2
I got error message below

  • PolyScope bundle ‘rs485-1.0.urcap’ is not valid, The manifest file (‘META-INF/MANIFEST.MF’) is missing.

There are no ways to control tool voltage and rs485 communication at UR3e Arm. T.T
