Hi
I’m trying again to setup a dev environment on my Debian 12 computer following tho official HA dev documentation.
I go the way with VSC although I’m very annoyed by the fact to install Microsoft stuffs to write open source code !
So far I think I have succeeded to setup the dev environment including Docker and so according at ha dev doc I tried to create the scaffold script to create the structure of the integration automatically.
I run the python command in the terminal of the dev instance of HA in VSC. I answer all the questions (it’s an integration basic for command through telnet of some video devices) and then at the end it executes the script that fails with that:
Scaffolding config_flow for the blustreamacm integration...

Any ideas what’s wrong there as my basic knowledge of python are lost there 
Thanks
