I keep getting errors that my modules don't exist when I'm running nodemon inside Docker and I save the node files. It takes a couple of saves before it throws the error. I have the volumes mounted like how the answers suggested here but I'm still getting the error and I'm not too sure what's causing it.
Here is my docker-compose.yml file.

Here is my docker file:
