The method
shouldSnakeAttributes does only exist in Encore\Admin\Form , but not in Encore\Admin\Widgets\Form .
It seems like the method you are trying to call exists only in some of the possible types. Let’s take a look at an example: class A
{
public function foo() { }
}
class B extends A
{
public function bar() { }
}
/**
* @param A|B $x
*/
function someFunction($x)
{
$x->foo(); // This call is fine as the method exists in A and B.
$x->bar(); // This method only exists in B and might cause an error.

Add an additional type-check:
Only allow a single type to be passed if the variable comes from a parameter:
