Error when trying to run 'php artisan route:cache'

[PaulChase]

• Laravel Version: 8..4
• PHP Version: 7.4.3
• Database Driver & Version: mysql Ver 8.0.26-0ubuntu0.20.04.2 for Linux on x86_64 ((Ubuntu))

Description:

I have a live laravel website running on aws ebs.
I entered the admin panel with laravel voyager to run some php artisan commands with laravel voyager compass.
I first ran 'php artisan view:cache' and it cached sucessfully.
Then I tried 'php artisan route:cache' and 'php artisan config:cache' and there were giving me the error
'Trying to access array offset on value of type null'
as also shown in the image below
what can I do to solve this issue?

Should be asked on stackoverflow. But it looks like to me you haven't installed Laravel properly and it's missing config/.env.

i think your config/session.php is missing for some reason, or there is an issue with it, like a return null

try to use tinker and see what config('session') returns.

php -r "echo null['test'];"
PHP Notice:  Trying to access array offset on value of type null in Command line code on line 1

try to delete the cache manually,
remove bootstrap/cache/packages.php, bootstrap/cache/services.php
and storage/framework/cache/data/*
