API server not working

[Sondos]

Hi

I’m working on a self-hosted version right now (I cloned it before two weeks)
I did create a custom piece (community type)

i couldn’t find my piece when i start creating a new flow , even though i added all the necessary codes and packages i have been told on discord

so i asked Gemini AI , and it said that i have to run this command :

npx nx run-many --target=build --all

but i got an erore message saying that the API server is not working and these are the screenshots for the error message :

one thing i forget to say
i’m working on Linux system ( Fedora )

Hi Sondos, please click on “Apps” in the piece selector, and you will see the piece, this is something we will soon fix for the dev env:
