Undefined index: password with JWTAuth - json

Question

hello I have a problem with the password field to create a user in laravel for a restfullapi
public function store(Request $request)
{
$this->validate($request,[
'user_names' => 'required||string|max:45',
'user_lastnames' => 'required|string|max:45',
'user_email' => 'required|string|email|unique:users,user_email|max:150',
'user_password' => 'required|string|min:6|confirmed',
'user_password_confirmation' => 'required|min:6',
'user_gender' => 'required',
'user_celphone' => 'required|numeric',
'user_origin_country' => 'required|string|max:100',
]);
$user_names = $request->input('user_names');
$user_lastnames = $request->input('user_lastnames');
$user_email = $request->input('user_email');
$user_password = $request->input('user_password');
$user_password_confirmation = $request->input('user_password_confirmation');
$user_gender = $request->input('user_gender');
$user_celphone = $request->input('user_celphone');
$user_origin_country = $request->input('user_origin_country');
$user = new User([
'user_names' => $user_names,
'user_lastnames' => $user_lastnames,
'user_email' => $user_email,
'user_password' => bcrypt($user_password),
'user_gender' => $user_gender,
'user_celphone' => $user_celphone,
'user_origin_country' => $user_origin_country
]);
$credentials = [
'user_email' => $user_email,
'user_password' => $user_password
];
if ($user->save()) {
$token = null;
try {
if (!$token = JWTAuth::attempt($credentials)) {
return response()->json([
'error' => 'El email ó la contraseña son incorrectos'
],404);
}
} catch (JWTAuthException $e) {
return response()->json([
'error' => 'failed_to_create_token',
],404);
}
$user->signin = [
'href' => 'api/v1/user/signin',
'method' => 'POST',
'params' => 'user_email, user_password'
];
$response = [
'success' => 'Usuario creado exitosamente',
'Usuario' => $user,
'token' => $token
];
return response()->json($response, 201);
}
$response = [
'error' => 'Ha ocurrido un error'
];
return response()->json($response,404);
}
I'm testing the application with postman and he tells me this

I have verified the routes and it works, before placing the jwt I saved the data in the db without password problems, thanks in advance
