Answer 1

The error was thrown because one of the values in the .env file may have spaces.

Just enclosed any values with space in double quotes.

For example let's assume that this is part of your .env file

APP_ENV=local
APP_DEBUG=true
APP_KEY=This Will Cause An Error

DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

....

APP_KEY=This Will Cause An Error will cause this issue because it needs to be in quotes like:

APP_KEY="This Will Work"

Also any space after the values may cause the same issue too

Answer 2

In my case the reason for this error was a missing php extension. Since this missing extension raises an error, the logger tries to log it. This exception appears as a result of no 'log' class resolved from the container. I think this is a Laravel bug.

Answer 3

Check your Apache user and file system user first. Then run the following commands to set file system permissions:

sudo chmod 755 storage -R
sudo chmod 755 vendor -R
sudo chmod 755 bootstrap -R

After you finished changing the file permissions, clean your chache with the following commands:

php artisan config:cache
php artisan cache:clear
php artisan config:clear

This works for me.
