namespace App\Http\Controllers;

use Illuminate\Support\Facades\Storage;
use Illuminate\Http\Request;
use App\User;

class UserController extends Controller{

   /**

   }

   /**

      return(view("user.profile")->with(["user" => $user]));
   }

            }else{
               Storage::delete($user->profile_picture);
               $path = Storage::putFile("public", $request->file('profilePicture'));
            }
            $user->update(["profile_picture" => $path]);
         }
      }
      return(redirect()->route("user.profile", ["e_mail" => $user->e_mail]));
   }

   public function bio(Request $request){
      $user = User::where("e_mail", $request->e_mail)->first();
      if($request){
         $user->update([
            "occupation" => $request->occupation,
            "biography" => $request->biography
         ]);
      }
      return(redirect()->route("user.profile", ["e_mail" => $user->e_mail]));

Answer 1

Just change these routes

Route::post("user/profile_picture", "UserController@profilePicture")->name("user.profilePicture");
Route::post("user/bio", "UserController@bio")->name("user.bio");

to...

Route::get("user/profile_picture", "UserController@profilePicture")->name("user.profilePicture");
Route::get("user/bio", "UserController@bio")->name("user.bio");

done.

Try this use get method

Route::get("user/profile_picture","UserController@profilePicture")->name("user.profilePicture");

Route::get("user/bio", "UserController@bio")->name("user.bio");
