Laravel5.8 update image. Call to a member function store() on null

I am creating profile edit function in my laravel project.

I want to update profile image. When I upload a new image, I can see a new image in profile/index.blade.php.

But when I didn't upload an image, I could not see any image in profile/index.blade.php. And I got an error which says

Call to a member function store() on null

Profile edit page is profile/create.blade.php. And when I hit save button, I can redirect to a profile page, profile/index.blade.php.

What I want to accomplish is,

when I upload a new image, I want to show a new profile on index.blade.php. And if I don't upload an image, I want to redirect to index.blade.php and show a previous profile image.

I have profile folder in my Storage. I have already done php artisan storage:link.

UserController.php

public function store(Request $request, Profile $profile)
{
    $user_id = auth()->user()->id;

    $data = $request->only(['image']);

    if($request->hasFile('image')){
        //upload it
        $image = $request->image->store('profile');

        //delete old image
        Storage::delete($profile->image);

        $data['image'] = $image;
    } else {
        $image = $request->image->store('profile');
    }


    Profile::updateOrCreate(
        ['user_id' => $user_id],
        [   
            'image' => $image,
            'gender' => request('gender'),
            'country' => request('country'),
            'bod' => request('bod'),
            'instagram' => request('instagram'),
            'description' => request('description'),
        ]);


    //redirect user's profile page
    return redirect()->route('profile.index');
}

index.blade.php

<div class="person">
                    @if(empty(Auth::user()->profile->image))
                    <img src="" >
                    @else

                    <img src="" >
