Environment:<\/strong>
Laravel Version: 5.5
PHP Version: 7.4.0<\/p>\n\n\n\n

Error stack trace:<\/strong>
Message: Trying to access array offset on value of type null<\/code><\/p>\n\n\n\n

Sample code that gave me error:<\/strong>
$filterConfig = $request->get('filterConfig', null);<\/code>
$showAll = $filterConfig['show']['all'] === 'true'? true: false;<\/code>

The error was coming because $filterConfig was getting initialized by null in the first line and I was fetching $filterConfig[‘show’][‘all’] in the second line. Hence, it was throwing an error by saying Trying to access array offset on value of type null

NOTE:<\/u><\/strong> This error only comes if you have upgraded to PHP 7.4<\/strong><\/p>\n\n\n\n

Solution:<\/strong>
<\/p>\n\n\n\n

if (isset($filterConfig) && isset($filterConfig['show']['all'])) {
$showAll = true;
} else {
$showAll = false;
}<\/code><\/p>\n\n\n
