array_map(): Argument #2 should be an array

I'm getting this errorarray_map(): Argument #2 should be an array when a user trying to create a product

I changed my code from this solutions How to make each authenticated user only see their own product, and now it gives me that error.

ProductController

class productController extends Controller
{

public function index(Request $request)
{
    $userId = $request->user()->id;
    $products = products_model::where('user_id', $userId)->get();
   return view('seller.product.index',compact('products'));
}




public function create()
{  
    return view('seller.product.create');
}

public function seller()
{
   $products=products_model::all();
   return view('seller.product.index',compact('products'));
}


public function store(Request $request)
{

    $formInput=$request->except('image');
    $this->validate($request, [
     'pro_name'=> 'required',
     'pro_price'=> 'required',
     'pro_info'=> 'required',
     'users_id' => \Auth::id(),
     'image'=>'image|mimes:png,jpg,jpeg|max:10000'
    ]);

    $image=$request->image;
    if($image){
        $imageName=$image->getClientOriginalName();
        $image->move('images', $imageName);
        $formInput['image']=$imageName;
    }

    products_model::create($formInput);
    return redirect()->back();
}


public function show($id)
{
    //
}


public function edit($id)
{
    //
}


public function update(Request $request, $id)
{
    //
}


public function destroy($id)
{
   $userId = $request->user()->id();
   $deleteData=products_model::where('user_id', $userId)->findOrFail($id);
   $deleteData->delete();

   return redirect()->back();
}
}

Products_model

class products_model extends Model
{
protected $table='products';
protected $primaryKey='id';
protected $fillable= ['user_id','pro_name','pro_price','pro_info','image','stock','category_ id'];
}

Products table

class CreateProductsTable extends Migration
{

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('pro_name');
        $table->integer('pro_price');
        $table->text('pro_info');
        $table->integer('stock');
        $table->string('image')->nullable();
        $table->timestamps();

        $table->bigInteger('user_id')->unsigned()->index();
        $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    });
}


public function down()
{
    Schema::dropIfExists('products');
}
}

I want every user to be able to create and delete his own product without interfering other users.
