Deploying ExpressJs app with buildpack

I ran a test project with your package.json and it works just fine. I guess there’s something wrong with your code. Make sure your Express App listens on port 3000. And if your app uses environment variables, set them in Qovery console.

One thing you might try adding in package.json is the “engines” property where you can specify the version of node and npm.

"engines": {
        "node": "14.x",
        "npm": "7.x"
}
