I have this app:
It works fine locally (see running instruction in README).
However Push to Deploy fails with errors like these:

Maybe this is because the Push to Deploy script runs meteor npm install, but locally I use npm directly by running npm install. I prefer being on current tooling. meteor npm is at 6.14, while npm is 8.6.
So far I’ve tried to use Push to Deploy for 4 apps, but zero of them successfully have Push to Deploy enabled. 
Push to Deploy needs some smoothing, needs to reflect environments more similar to what developers actually use.
Btw, is it possible to install system dependencies? I think that would help with this issue, as well as Push To Deploy is unable to install dependencies
