Module Not Found When Run on Docker-Compose

I'm preparing a Dockerfile that will be used in production. But for some reason, the last command is returning an error.

react_1  | [WEBPACK] Building 1 target
react_1  | [WEBPACK] Started building bundle.[chunkhash].js
react_1  | [WEBPACK] Build failed after 33.631 seconds
react_1  | [WEBPACK] Errors building bundle.[chunkhash].js
react_1  | Module not found: Error: Can't resolve './App' in '/home/app/react/src'

Here is the copy of the docker file

Dockerfile.prod

FROM node:7.10.1-alpine

RUN apk update
ENV HOME=/home/app
COPY . $HOME/react/
RUN npm install yarn -g

WORKDIR $HOME/react
RUN mkdir build && mkdir dlls && yarn

CMD ["yarn", "start:prod"]

Here's the copy of the docker-compose file

docker-compose.prod.yml

version: '3.1'
services:
  react:
    build:
      context: .
      dockerfile: Dockerfile.prod
    ports:
      - 3100:3100
    volumes:
      - /home/app/react

When I docker-compose -f docker-compose.prod.yml up --build -d it works as expected until when it builds the webpack file. But fails as you can see in the error above.

But when I do this docker-compose run react yarn start:prod the webpack builds just fine.

Here's the repo in question.

My bad. It was case sensitive errors. Since I was on windows it just went through without problems.

So the error happened because the import statement was finding App folder, but the actual folder was app.
