Github Actions deploy artifacts - github

Question

Below workflow fails when deploying the artifacts to S3. In the last line, in the deployment job, it's complaining that ./build doesn't exist, probably because it can't find the artifacts.
The user-provided path ./build does not exist.
##[error]Process completed with exit code 255.
How do I make it recognise the artifacts created in the build job?

You need to download the artifact in the deploy job. See the actions/download-artifact action.
deploy:
name: Deploy
needs: build
runs-on: ubuntu-18.04
steps:
- uses: actions/checkout#master
- name: Download Artifact
uses: actions/download-artifact#master
with:
name: build
path: build
- name: Deploy to S3
env:
AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
run: |
aws s3 cp \
--recursive \
--acl public-read \
--region ap-southeast-2 \
./build s3://example
