HTML to PDF Action - NodeJS & PHP [Open Source]

I’m quite lost. My complete docker file is the original that Wappler creates automatically when you start a new proyect with those lines I previously copied (I’m not with my Mac right now).

After 4 hours of research, I gave up. I really don’t know how to implement the chromium and puppeteer service on the same image that runs Wappler’s web app. Maybe I should create a new image with those two services? There’s documentation and proyects to clone where you can start a Docker machine runing those services. But from what I understand, that won’t work because it would be separated from the web app, right?
