Argument 1 passed to Symfony\Component\HttpFoundation\InputBag::get() must be of the type string, null given, called in D:\Syed Ghazanfar\Futafut\Backend\v2\vendor\laravel\framework\src\Illuminate\Session\Middleware\StartSession.php on line 157

Hi, I got this error in my laravel project, Basically I moving laravel 5.8 to laravel 7.29 then I received this error,

can anyone help me in this error.

The bug happens in Laravel, not in Symfony. Please report it to them.

Passing null as parameter name in InputBag::get() has never been a supported use case (it was documented as string since Symfony 2.0.0 on the bag class used at that time). So if their middleware passes null, it has a bug.
