RuntimeException Session store not set on request.

Hi,

I was watching episode 19 from the Laravel 5.4 From Scratch series, when I got this error at around 15 minutes. I tried to undo most of the changes I made, but the error still persists. I've been stuck on this for a while now, and I would be really thankfull if someone could help me.

Error report:

"Session store not set on request."

In vendor\laravel\framework\src\Illuminate\Http\Request.php

Code:

    public function session()
    {
        if (! $this->hasSession()) {
            throw new RuntimeException('Session store not set on request.');
        }
 
        return $this->getSession();
    }

Application frames (1)

in Illuminate\Foundation\Http\Kernel handle

code:

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

Here are some of my files. I didn't include most of the files I didn't work on for a while. Please ask for more files if needed.
