Error while debugging other python projects

I get a Unhandled: on_readmemory_request not available in PyDevJsonCommandProcessor. error while debugging other python projects. This issue gets resolved when I disable the STM32Cub for Visual Studio Code Core extension and its related extensions.

To reproduce: 

Open an existing python project or package (workspace)

Launch the debug session. 

It tries to start the session and in a few seconds throws this error and stops the debugger.

Unhandled: on_readmemory_request not available in PyDevJsonCommandProcessor.

    Maybe good practice is to rely on VSCode's profiles what are promoting some isolation kind: https://code.visualstudio.com/docs/configure/profiles

      Hi @Nawres GHARBI ,

       

      We have the same problem here.

      Can we have an update on the solution ?

      Or maybe a link to the issue feed?

       

      Thanks,

      Arnaud

      Sadly, the ST ticketing system is internal and not visible to customers.

      Usually, ST people make this clear when referring to internal tickets; eg, here.

      A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
