What node versions did you try? I believe the way you’ve declared the engine dependency will require that exact version of node on the builder. Can you try “node”: “>=10.0” or “node”: “^10.0” instead?
What base image are you using for this build?
Ideally you can set you engine by using one of the nodejs base images and setting the engine version there (...-node:10-...), see more info here, if you want to check it out https://www.balena.io/docs/reference/base-images/base-images/
