When I try to start a custom docker image with a specified location it does not work

I have been working on a Docker file for the past couple days and when I go to start it, it will work if I don’t specify a location but when I specify a location it dose not copy anything it needs to that location. here is my docker file

FROM ubuntu:jammy

WORKDIR /usr/local/spacebar-server

RUN apt-get update && apt-get upgrade -y && apt-get install curl -y

RUN cd ~ && curl -sL https://deb.nodesource.com/setup_16.x -o /tmp/nodesource_setup.sh && bash /tmp/nodesource_setup.sh && apt-get install nodejs

COPY ./spacebar /usr/local/spacebar-server

RUN apt-get install software-properties-common -y && add-apt-repository ppa:deadsnakes/ppa

RUN apt-get install build-essential git python-is-python3 -y 

RUN npm install -g npm

RUN npm i

RUN npm run setup

CMD npm run start

Back when I made Docker files I never had a workdir so I tried to remove it but that didn’t work since npm install needs a workdir. This is the error I get from docker when I start it

I have tried docker compose but it has the same outcome. any ideas why its doing that?

I have tried to remove the workdir but that didn’t work I can’t think of anything else I can do
