Chapter 9. Pkg Application - Nodejs Result App issue. Won't start. Outdated Nodejs.

Hello, I am having trouble making a docker image for Nodejs result app.

For starters, Nodejs 8.16 is not officially supported.

For this reason,** npm test **fails.

I used Node12 and made an image and npm test succeeds now.

However, npm start /app fails with the error below.

Can someone help me, please? Is it a code vs. Nodejs version problem?

Thanks - Nick

/app # npm start /app

[email protected] start /app
node server.js "/app"

/app/server.js:12
io.set('transports', ['polling']);

    Hi,

    I had the same issue and solved it by using the same version of node JS as in the course: node:8.9.0

    node:8.9.0

  • Hi @fredlev , thanks for confirming the fix!

    Regards,
    Luis.

    Even though its outdated, you should be using node:8.9.0 as @fredlev suggested above. This is what is compatible with the code in the repo.
