The module is called MenuZFV and has a .js file as well as .css and also a node_helper.js which I paste below. The problem is the data can be accessed from the website: (‘https://app.food2050.ch/de/stfw/restaurant -stfw/menu/mittagsmenue/weekly?week=26’) cannot be accessed. Npm install in the folder was done. ChatGPT recommended puppeteer to me because there is no DOM on the website, I installed it via npm install, but when I run node node_helper.js this log comes up - can anyone help me?

LOG:
