Laravel trying to access array offset on value of type null

Error type: trying to access array offset on value of type null

Solution 1:

If you encounter such error in Laravel you need to only run this command.

php composer.phar update

or

composer update

That will fix the issue!

Solution 2:

This issue may due to that fact you are running old Laravel versions in a system using recent PHP versions. In such case, you can also do the following.

Change the PHP version in Composer.json to 7.4.* and and then run:

php composer.phar update

or

composer update
