It looks like you need to check your package.json file, knowing your file structure might help. Maybe a bad pathway. Also are you installing this locally? I’ve had to configure node version manager on servers for example.

I wanna say it’s trying to look inside your app file instead of the parent folder.

Hello.
It becomes a quite long time the last time I used docker.
But you can run your container (not sure if it is mandatory).
and then connect to its shell with docker exec command.

So type something such as
docker exec -it container_id_or_name sh

Then you’ll do such commands

cd /
ls -l
cd /app
ls -l

ls -l should display the user and group of your files along with permissions represented as number or letters such as 0644 or rw-r--r-- .
Check if it is set properly.

Cheers.
