[RuntimeException] Source path "./nova" is not found for package laravel/nova

Hi All,

I'm hoping someone can help me out here! I have installed nova and been testing it locally...works perfectly! When I went to deploy it through laravel forge I got this error

[RuntimeException]                                          
Source path "./nova" is not found for package laravel/nova

ssh key is all good, I'm thinking that I might be missing something on my forge script or env file or it might have something to do with nova authorisations? I've been looking around and I can't seem to find the solution.

here is my forge script

cd /home/forge/ninetyfourmagazine.co.uk
git pull origin master
composer install --no-interaction --prefer-dist --optimize-autoloader

php artisan config:cache

echo "" | sudo -S service php7.2-fpm reload

if [ -f artisan ]
then
    php artisan migrate --force
fi

Here is my composer.json

any advice would be much appreciated.
