function $request->validated() changed it's behavior

[abutir]

• Laravel Version: 8.53.0
• PHP Version: 7.3.19

Description:

I use form requests all over my app, and use $request->validated() to only use the validated data from the request.
sometimes I have keys that are optional, and I don't want to attach a rule to them, so I simply define them with a rule as an empty string. this used to work just fine.

if I try to use any package, composer updates this function to a new behavior.
I have used this function over 150+ times in my app, what can I do to fix this !! (without refactoring the code)
I'm unable to use packages anymore.

Steps To Reproduce:

• make a form request.
• add rules like this : 'type' => '' , 'type2'=>'required|nullable'
• go to your controller and simply retrieve $request->validated() , only type2 will appear .
