Setting unknown property: yii\web\UrlRule::GET

Question

I have this error and I don't know to solved.

I created an api endpoint with Yii2. A few days ago the endpoint was working but now it doesn't and raise this error:

{
name: "Unknown Property",
message: "Setting unknown property: yii\web\UrlRule::GET index",
code: 0,

There is my urlManager configuration:

modules' => [
        'v1' => [
            'basePath' => '@app/api/modules/v1', // base path for our module class
            'class' => 'app\api\modules\v1\Api', // Path to module class
        ]
    ]
'components'  => [
        'urlManager'  => [
            'enablePrettyUrl'  => true,
            'showScriptName'  => false,
            'enableStrictParsing' => false,
            'rules' => [
                'class'  => 'yii\rest\UrlRule',
                'controller'  => 'v1/demo',
                'patterns' => [
                    'GET index' => 'index'
                ]
            ],
        ],

I created this simple example with a Demo controller and a simple index endpoint in order to show to get a more clear picture about the problem.

How can I solve this problem? why is return unknown property.

        }
    }
}

If you need more information just lemme know but I need to solve this problem now or I'll be a crazy man without return.

Update: Controller

It is my controller:

<?php

namespace app\api\modules\v1\controllers;

use yii\rest\Controller;

class DemoController extends Controller
{
    public function behaviors() {
        return [
            [
                'class' => \yii\filters\ContentNegotiator::className(),
                'formats' => [
                    'application/json' => \yii\web\Response::FORMAT_JSON,
                ],
            ],
        ];
    }

    public function actionIndex(){
        return "index ";
    }
}

Yii2 routing guide

I did these configuration following the official guide about Routing:

[
    'class' => 'yii\rest\UrlRule',
    'controller' => 'user',
    'extraPatterns' => [
        'GET search' => 'search',
    ],
]

Answer 1

wow, thank you guys. I had been working the whole weekend trying to solve this problem and based on your feedback and researching I found a little error in the configuration. In Yii2 guide explain the configuration in two piece of code. So I had to change my code from this:

'rules' => [
    'class'  => 'yii\rest\UrlRule',
    'controller'  => 'v1/demo',
    'extraPatterns' => [
        'GET index' => 'index'
   ]
]

to this one:

'rules' => [
    [ // array item
      'class'  => 'yii\rest\UrlRule',
      'controller'  => 'v1/demo',
      'extraPatterns' => [
          'GET index' => 'index'
       ] 
    ]//close the array item
]

Well, the error is gone.
