Previously I had a problem with build artifacts not being created because it wasn't running the V1 buildkit build system. Brody assisted in changing it for me (I believe I can't change these things myself - I need admin support). Said service is now working, however I have another service that is experiencing the same issues - I need it to go back to V1.
As an aside, I'm happy to assist if you want to debug why V2 isn't working for us...
