express module not found when trying to run standalone server

[RickyChan21]

When trying to run the container after building it with the Dockerfile provided, I get the following error related to the express module:

> iqbit@1.0.1 server-docker-start /usr/src/node-app
> cd server && npm run serve:docker


> standalone-iqbit-server@1.0.0 serve:docker /usr/src/node-app/server
> node server.js

Sounds like we're missing a step to run "npm install" before those other commands.

You can try manually running it in the server folder if you nodejs installed

Thank you, it's working now after running "npm install express" on the server folder.
