White screen after install

[Sneethan]

Hey there.. I am trying to install this on a VPS and ran into a few issues -

```Warning] Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1


su www-data -s /bin/bash --command="cd /var/www/html && npm install"
[============================] (Done!)
su www-data -s /bin/bash --command="cd /var/www/html && npx mix -p"
[============================] (Done!)
su www-data -s /bin/bash --command="cd /var/www/html && php artisan key:generate"
[============================] (Done!)
[Warning] The environment file is invalid!
Failed to parse dotenv file. Encountered a missing closing quote at ['UNIT3D].


su www-data -s /bin/bash --command="cd /var/www/html && php artisan migrate --seed"
[============================] (Done!)
[Warning] The environment file is invalid!
Failed to parse dotenv file. Encountered a missing closing quote at ['UNIT3D].```

When attempting to load the "installed" website i get this page.

any help would be appreciated.
