The --delete flag will remove files from S3 that don't exist locally, which could lead to unintended data loss. Consider adding error handling or removing this flag if not necessary for the deployment strategy.

Suggested change

	aws s3 sync ./dist s3://${{ secrets.AWS_S3_BUCKET }} --delete
	aws s3 sync ./dist s3://${{ secrets.AWS_S3_BUCKET }}

[Copilot]

Consider adding error handling and validation before the S3 sync operation. The build could succeed but produce an empty or invalid dist directory, which would then sync to S3.

Suggested change

	run: yarn build
	run: yarn build
	- name: Validate dist directory
	run: |
	if [ ! -d "./dist" ] || [ -z "$(ls -A ./dist)" ]; then
	echo "Error: dist directory does not exist or is empty. Aborting deployment."
	exit 1
	fi
