Node-RED 'projects' possible on netPI?

[JG_KIT]

Hi,

I thought of using the 'projects' feature of Node-RED to save my flows on GitHub.
I found tutorials saying, that setting this variable:
   
will work an apparently it does try:
   
however, fails when trying to find 'git'.

So, I wondered, is this image of Node-RED that is supplied under 'HilscherAutomation/netPI-nodered' on GitHub able to use projects (has git included) and I am doing something wrong or do I need another option than that to back up the content of my Node-RED container (and possibly import them on other netPI devices)?

Thanks a lot in advance.

Best regards,
Johannes
