The call to SilverStripe\Forms\GridF...tailForm::__construct() has too many arguments starting with false.
Ignorable by Annotation
If this is a false-positive, you can also ignore this issue in your code via the ignore-call annotation
$this->addComponent(/** @scrutinizer ignore-call */ new GridFieldDetailForm(null, false, false));
This check compares calls to functions or methods with their respective definitions.
If the call has more arguments than are defined, it raises an issue.
If a function is defined several times with a different number of parameters, the
check may pick up the wrong definition and report false positives. One codebase
where this has been known to happen is Wordpress. Please note the @ignore annotation hint above.
