im getting a 503 back from that endpoint

are you seeing any errors in your deploy logs?

some errors, but idk if are related to this case

ahh ok, i just see a error related to puppeteer library, must be that, im going check

For that, I would highly recommend using the browserless template instead of installing chrome into the container.

here is an example repository on how you would use the browserless template with puppeteer -

Please read the README for instructions.
