Notice: Undefined property: Config \ App :: $ cookieSameSite

I am running the CodeIgniter 4 develop version and it runs fine that key should be.

PHP Code:

public $cookieSameSite = 'Lax'; 


If your on an older version of CodeIgniter 4 that could be why your getting that error.

What did you Try? What did you Get? What did you Expect?
