Summary of the issue I am facing:
I cannot properly setup AppApi 
I have followed the steps described in the documentation (via both methods, first setting HaRP then Docker Socket Proxy docker containers).
I am able to get the Daemon properly connected but never manage to test the whole setup with “Test deploy” which seems to fail even before starting.
In the NC logs I get the following error message (this one is for Docker Socker Proxy method but I get the similar error for HaRP) :
