Why does AWS amplify does not recognize updated node version?

Question

I upgraded node on my local machine as well as migrated from create-react-app to nextjs.

When I pushed my code to AWS Amplify, I got this error:

error [email protected]: The engine "node" is incompatible with this module. Expected version ">=12.22.0". Got "12.21.0"

error Found incompatible module.

info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

I've looked on stackoveflow and other blogs and I've tried everything, but I still get this error.

My trials:

• Added engines: node to my package.json

"engines": {
    "node": ">=12.22.0"
  }

• Ran these commands:

sudo npm cache clean -f
sudo npm install -g n

• Double checked my node version:

node -v                                                                              
v16.13.0

• Deleted and then installed the node modules folder with yarn install

Why is this error still occurring?

Answer 1

You are only using node v16 locally, amplify for some reason uses a lower one. You could either downgrade the package (not recommended imho) or tell amplify to use a higher node version (recommended imho).

  phases:
    preBuild:
      commands:
        - nvm install 16
