The original post refered to NullPointerException when trying to Run/Debug the project.

I’m having the same issue. The project builds successfully and I can flash it onto the target with ST-Link utility. However, when trying to Run/Debug in System Workbench, I get the following error:

An internal error occurred during: “Launching
STM32F4xx-Nucleo Debug”.
java.lang.NullPointerException

Here’s my log:
