Why is package.json ignored when running Vue from a docker container?

Question

Docker

Hey guys, why isn't Vue running in a docker container ?

docker run -it -d --name project_name -p 3001:8080 -v /home/username/PhpstormProjects/project_name/cabinet:/app username/project_name

Dockerfile :

FROM node:17.3-alpine
ARG APP_DIR=/app
ARG LOCAL_APP_PATH=cabinet
RUN mkdir -p ${APP_DIR}
WORKDIR ${APP_DIR}
COPY ${LOCAL_APP_PATH}/package*.json ./
RUN ls -al
RUN npm i;
EXPOSE 8080
CMD npm run serve

This snippet shows when building that package.json is present

Step 7/10 : RUN ls -al

I type in:

docker logs d57e7227eb10

I get:

At the same time, the installation inside proceeds during the build and the build completes without errors:
