Gitlab-ci fails at copying files - reactjs

Question

I'm using gitlab-ci and gitlab runner to deploy my React app to my server.
Here is my code:
image: node:alpine
variables:
PUBLIC_URL: https://example.com
stages:
- build
- deploy
build:
stage: build
tags:
- some-tag
- another-tag
script:
- echo "Building deploy package"
- pwd
- npm install
- mv .env.example .env
- echo ".env file changed!"
- CI='' npm run build
- echo "Build successful"
- ls
artifacts:
expire_in: 1 hour
paths:
- build
only:
- master
deploy_production:
stage: deploy
tags:
- some-tag
- another-tag
script:
- echo "Current Directory:"
- pwd
- ls
- echo "Deploying to server"
- cp -rv ./build/* /dir/path-in-my-server/
- echo "Deployed"
artifacts:
expire_in: 1 hour
paths:
- build
environment:
name: production
url: https://example.com
only:
- master
Every steps works well, but cp -rv ./build/* /dir/path-in-my-server/ is not working. It giving this error:
cp: can't create '/dir/path-in-my-server/asset-manifest.json': No such file or directory
cp: can't create '/dir/path-in-my-server/favicon.ico': No such file or directory
cp: can't create '/dir/path-in-my-server/index.html': No such file or directory
cp: can't create '/dir/path-in-my-server/manifest.json': No such file or directory
cp: can't create directory '/dir/path-in-my-server/static': No such file or directory

What am I missing?

I fixed this issue by using $PWD env variable instead of relative paths like ./. GitLab seems to have a problem with relative paths in cp and mv commands.
script:
- cp -rv ${PWD}/some-directory/* /your-dest-dir/
