Undefined array key "permissions"

I have this tables:

users
permissions
roles
role_user
permission_user
permission_role

Giving permissions to roles on my system works well.

I Want When set a role for a user,Automatically apply permissions to that user.but it gives the error

Undefined array key "permissions"

User Controller

    public function update(Request $request,User $user)
    {
        $data = $request->all();
        $user->update($data);
        if ($user) {
            $user->roles()->sync($data['roles']);
            $user->permissions()->sync($data['permissions']);
            return redirect()->action('Admin\UsersController@index')->with([
                'message' => 'User Successfully Updated',
                'messageTitle' => 'Update User'
            ]);
        }
    }
