Deploy script keeps throwing errors

[sausin]

I am trying get an Envoyer style zero-downtime deployment going. However, for the life of me, I can't figure out what I am doing wrong (hopefully just a simple oversight!).

Here is the deployment script:

# Validate required environment variables
if [ -z "${SITE_PATH:-}" ]; then
    echo 'Error: SITE_PATH is not set'
    exit 1
fi

if [ -z "${COMMIT_ID:-}" ]; then
    echo 'Error: COMMIT_ID is not set'
    exit 1
fi

# create the directory for latest code
mkdir -p "$SITE_PATH/deployments/$COMMIT_ID"
cd "$SITE_PATH/deployments/$COMMIT_ID" || exit

# get the code and install packages
cd $SITE_PATH
git fetch --all
git reset --hard origin/$BRANCH
git pull origin $BRANCH
composer install --no-interaction --prefer-dist --optimize-autoloader --no-dev

# linking
rm -rf storage/
ln -s "$SITE_PATH/storage" storage
ln -s "$SITE_PATH/.env" .env

# carry out prep tasks
php artisan migrate

# change path to latest app
ln -s "$SITE_PATH/deployments/$COMMIT_ID" "$SITE_PATH/latest"

# cache the new config and routes
php artisan config:cache
php artisan route:cache

This keeps throwing errors as below:

Try 'mkdir --help' for more information.

bash: -c: line 25: syntax error near unexpected token `||'

I have just replaced the domain name part in these logs. Would be awesome to get some help! The vito instance is version 2.2.1
