Double-check your Dockerfile.

"npm" is different from “npm”, notice the double quote " and “. You should always use " (input from your keyboard) rather than “

then run the following command:

docker-compose up --build

You could use the CMD instruction instead of RUN.

Change this line:

RUN ["npm", "start"]

...to this:

CMD ["npm", "start"]

The CMD instruction is triggered when your container starts.

Docs here: https://docs.docker.com/engine/reference/builder/#cmd

I hope this helps.
