This is the error that occurred upon running my build:

WARNING in configuration

This is my Dockerfile:

FROM node:12.10

 
WORKDIR /src

COPY package.json package.json
COPY yarn.lock yarn.lock

#Note the dependency install
RUN apt-get update && \
 apt-get -y install libcairo2-dev \
 libpango1.0-dev \
 libjpeg-dev \
 libgif-dev \
 librsvg2-dev

RUN yarn install
RUN yarn run build

EXPOSE 3000

COPY . . 

CMD ["node", "./server"]

You can find a copy of my webpack.config.js here.

I'm not sure if my webpack configuration is correct or if the source of the error lies in my Dockerfile. I look forward to your insight. Any help is greatly appreciated, thank you.
