Docker MongoDB - Why cant Docker Compose open any files

Question

I am trying to deploy a High Availability MongoDB for the first time and after a few hours of research, I found a good guide with a Git-Repository included to setup the MongoDB Replicas with a Docker Compose Script but I keep getting basically the same error for every file I want to open.

Error opening config file: Is a directory
mongo1                 | try 'mongod --help' for more information

I use for the Docker Desktop and VS Code for the Development.

Thanks a lot
