Hi everyone,

I'm experiencing issues with building my Docker container on Railway.app, which works perfectly on my local machine. I would greatly appreciate any assistance or insights from the community.

Project Details:

Base Image: Ubuntu 24.04

Python Version: 3.10

Additional Tools: Homebrew, GCC, FFmpeg

Issue Description:

The Docker build process fails when deploying to Railway.app. The same Dockerfile builds successfully on my local machine without any issues. Below is the Dockerfile I am using:
