Hi I used the dockerfile you had provided for creating docker image for my nodejs app(using loopback)

i appended below lines to the DockerFile you had shared to add my nodejs code.. at the step of "run npm install" am getting below-mentioned error message

WORKDIR app
COPY package.json .
RUN npm install
COPY . /app
CMD node server/server.js
EXPOSE 3000

Error:
