Cannot find any nodejs modules AWS Elastic Beanstalk

I'm trying to deploy my express server to AWS Elastic Beanstalk but keep running into the problem of modules not being found. I am using CodeBuild and a buildspec.yml to build and convert my code to an artifact.

Buildspec.yml

batch:
  fast-fail: true
phases:
  install:
    runtime-versions:
      nodejs: 16
  build:
    commands:
      - npm run build
artifacts:
  type: zip
  files:
    - "**/*"
  base-directory: build

Any help would be greatly appreciated.

You need to copy the node_modules in the build step. The way I do it is adding a post_build pahase.

post_build:
    commands:
        - cp -R node_modules/ dist/node_modules
