RUN npm install --silent
RUN npm install react-scripts@3.4.1 -g --silent

COPY . ./

# start app
CMD ["npm", "start"]

This basically happens when something is broken while docker tries to install JS packages. As the error code "254" stands for all types of installation failures, the only way to get the specific issue is by running the " install " or " ci " command without --silent .
