删除文件错误

Question

I am trying to delete a file after I delete the product from the database, but it shows me an error, and I cannot find a solution.

Call to a member function delete() on null

public function supprod($id,Request $request)
{
    $produits=Produit::find($id);
    $produits->delete();  // <-- error on this line
    $filename=(string)$document->nom;
    Storage::disk('fichier')->delete($filename);
    return redirect()->back();
  }

Image of the problem

Answer 1

this is check the record this function $produits=Produit::find($id); This use $produits=Produit::where('id',$id)->first();
