Error trying to find "isTCPAvailable" when running STM32CubeMonitor in TCP mode

[Wol]

I'm using JetBrains CLion to debug my STM32 project, and it runs `ST-LINK_gdbserver` when debugging, and passes the "--shared" flag for other STM apps to connect into. It starts up okay, and shows "Info : default port : 7184".

I've changed my "settings.js" file in "~/.STMicroelectronics/stm32cubemonitor/" folder so that "connectionType" is "tcp" and not "p2p".

I run stm32cubemonitor, and then node-red is showing up an error of:

 

Cannot read properties of undefined (reading 'isTcpAvailable') (line:59)

I think this code underneath is all bundled into the distributable, so I can't debug what's actually going wrong.

The versions I have installed currently are:

ii st-stm32cubeide-2.0.0 2.0.0-26820-20251114-1348-1 amd64 IDE for STM32

I'm using an ST-Link/V2 ISOL

Running on Ubuntu 25.10. 

 

 

Any ideas how to fix this, or where the source code is for that node-red module, or if it's a known error. Can't find any mention of this.
