EB deploy NodeJS app - npm failed to install dependencies

Question

appreciate any advice on below issue!

I am attempting to deploy an Node app to EB using eb deploy and--after the artifact is uploaded--am seeing errors in eb-engine log saying I didn't specify Node.js version and that npm failed to install dependencies.

Are the two issues related? Why does it think Node version is not specified? Is it possible to view the deploy artifacts on the EC2 instance to verify contents? I tried eb ssh, but I only have access to user home directory, which is empty.

Here's my package.json, which has Node version specified:

{
  "name": "test-web-app",
  "version": "1.0.0",
  "license": "MIT",
  "private": true,
  "scripts": {
    ...
  },
  "dependencies": {
    ...
  },
  "devDependencies": {
    ...
    },
  "engines": {
    "npm": ">=6.0.0",
    "node": ">=14.0.0"
  },
  "browserslist": []
}
