The property context does not exist. Did you maybe forget to declare it?

In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code:

class MyClass { }

$x = new MyClass();
$x->foo = true;

Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion:

class MyClass {
    public $foo;
}

$x = new MyClass();
$x->foo = true;

This code seems to be duplicated across your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.
