I assume that you know it's not being used because of the nixpacks prints in the build logs, am I correct in this assumption?

Is your Dockerfile named something other than Dockerfile, if so, what's it's name?

Is your Dockerfile located somewhere else other than the root directory or somewhere other than the root directory you have set in your service settings, if so, where is it located?

No, you're not correct. I'm quite a beginner.

The file is named Dockerfile, I know it's importante for Railway to auto-detect it.

The file is located in the root directory and the appropriate github is being used (https://github.com/tvog/n8n-bonfire-final). Please see attached.

Thanks for your help Brody.

Please attach your build logs -

https://bookmarklets.up.railway.app/log-downloader/

here are my deployments logs.
as you can see the good Dockerfile is not being used.
i don't understand why. everything seems correct (Dockerfiles, install.ffmpeg.sh and entrypoint.sh are in root folder).

I'm sorry but I asked for your build logs.

Sorry, here it is.

Your dockerfile is definitely being used, may I ask why you are installing ffmpeg in the first place?

I'm building an N8N automation that takes images to create a video.
Weird. I couldn't find the print statements in my logs. I'll check if it's working now.

Do you have N8N listening on host 0.0.0.0 and $PORT?

I'm not sure.

Right now I've the error "Problem in node ‘Code‘ Cannot find module 'fs' [line 1] dans mon noeud Code." while trying to require fs, path and child_process in a Code node. Trying to fix it.

Is it somehow related?

I'm sorry but I can't understand what you are asking.

Sorry. I'm trying to execute a Code node in N8N. It requires fs, path and child_process.

const fs = require('fs');
const path = require('path');
const { exec } = require('child_process');

It seems impossible to run such code cause I've this error : cannot find module 'fs' [line 1].
How can I fix that ? Is it related to what you say about listening on host 0.0.0.0 and $PORT?

No, modules have nothing to do with Host and Port, you will need to find out why fs is missing and apply the correct solution.

Perfect. I guess I just have to install fs like I did with ffmpeg.
Can you please elaborate on listening on host 0.0.0.0 and $PORT?

fs is a node module, it would not be installed the same way as ffmpeg.

I added Node.js and npm to my instance (please see attached).
But I still can't use them in N8N (error Cannot find module 'fs' [line 1]).
Do you know why?

You'll find my deploy logs attached for reference.

Up.

This error would not be platform specific in any way, try looking for answered solutions on sites like stack overflow.
