npm install express command is also required?

[glaforge]

Hmm, I might have to double check that one. Express is listed in the package.json dependencies, so that's strange it wouldn't find it.

I tried an npm install, and then npm start, and it worked for me, I could start my application. Would it be possible that you have not the right package.json content, where it would be missing express?

[glaforge]

FYI the package.json in the codelabs and in the github repo should look like this:

{
  "name": "thumbnail_service",
  "version": "0.0.1",
  "main": "index.js",
  "scripts": {
    "start": "node index.js"
  },
  "dependencies": {
    "@google-cloud/storage": "^4.0.0",
    "body-parser": "^1.19.0",
    "express": "^4.16.4",
    "bluebird": "^3.5.0",
    "imagemagick": "^0.1.3"
  }
}

I am pretty sure I followed the instructions step by step and didn't experiment at all, but unfortunately I already have the project down and removed. I think this issue can be closed at least until someone confirms and reproduces the issue. Thank you.
