can't get a n8n with puppeteer deployment to work correctly

[Nafalan]

Hello

For the past 2-3 weeks I've been hammering away at this problem and have gotten so close but just can't get the final bit to work.

I'm using dokploy on my server to deploy my containers and manage env variables and domains and all that good stuff but I am trying to make N8N work with puppeteer and I get the error saying it requires lib and chrome dependencies.

After searching and troubleshooting I managed to figure out you need to make your own image of n8n that has puppeteer installed. I've done this but can't get the last bit to work to actually access the container.

I keep getting bad gateway but if I refresh it multiple times it will load the setup then when I press submit it gives a 502 error message.

Can someone proficient in dokploy and docker compose help me out with this please. I'm using a compose file for my deployment. I just don't understand the configuration required to get this last bit to work
