Route Model binding fails when using Form request - laravel

Question

The Route model binding fails when I use the FormRequest to validate the request. To be more specific, when I try to access the parameters in the form request and give the following error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'name:\"moniersa\"' in 'where clause'
(SQL: select count(*) as aggregate from `users` where `email` = a.monier2130#gmail.com and
`name:\"moniersa\"` <> {\"id\":5 and `email:\"a`.`monier2130#gmail`.`com\"` =
email_verified_at:null and `admin:1` = verified:0 and `created_at:\"2020-02-11 22:33:33\"` =
updated_at:\"2020-02-11 23:17:40\"})
The code of the update method:
public function update(User $user, UpdateUserRequest $request)
{
$data = $this->extract_data($request);
$user->update($data);
return response()->json(['data' => $user], 200);
}
The code of the rules function in the Update request:
public function rules()
{
return [
'name' => 'required|string|min:3|max:40',
'email' => 'required|email|unique:users,email,' . $this->user,
'password' => 'required|string|min:9|confirmed'
];
}
Whenever, I remove the User hint from the update method or $this->user from the update request file, everything works fine. Any clue about what is the problem is?

Route model binding means you do not need to use $user = User::findOrFail($user); anymore,
public function update(User $user, UpdateUserRequest $request)
{
$user = User::findOrFail($user);// this line is redundant, you can remove it.
$data = $this->extract_data($request);
$user->update($data);
return response()->json(['data' => $user], 200);
}
