sh: 1: nuxt: not found (Heroku/Nuxt)

Question

I've got a problem, I'm finally deploying a server-side nuxt app (with an express server) I've created to Heroku. The build succeeds but then when it tries to start it gives me:

2021-07-29T18:13:38.000000+00:00 app[api]: Build succeeded

I'm not sure where i'm going wrong with this. Do I have to build it before deploying with the Heroku cli? Is it a problem with my express server (since it's saying it failed at nuxt-express. I'm just not sure whats going on, if anyone could be of help it would greatly assist me! Thanks!

Here is my package.json if it helps:

Try changing your start script to be a path to nuxt/bin then provide the

Optionally if you still are having issues, consider adding the -c flag with the relative path to your nuxt.config.js file.

Do the same for build.

 "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start",
    "generate": "nuxt generate",
    "heroku-postbuild": "npm run build"
  },

to

 "scripts": {
    "dev": "nuxt",
    "build": "node_modules/nuxt/bin/nuxt.js build -c ./nuxt.config.js",
    "start": "node_modules/nuxt/bin/nuxt.js start -c ./nuxt.config.js",
    "generate": "nuxt generate",
    "heroku-postbuild": "npm run build"
  },
