Yii2 restful api object not found error - php

Question

I tried to install RESTful API module from this http://budiirawan.com/setup-restful-api-yii2/ and I am getting error
Object not found!
I tried setting mod_rewrite and also AllowOverride All configuration.
I also have connected it to correct database and that database has country table in it.
I also have .htaccess file and here is my api/config/main.php file
<?php
$params = array_merge(
require(__DIR__ . '/../../common/config/params.php'),
require(__DIR__ . '/../../common/config/params-local.php'),
require(__DIR__ . '/params.php'),
require(__DIR__ . '/params-local.php')
);
return [
'id' => 'app-api',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'modules' => [
'v1' => [
'basePath' => '#app/modules/v1',
'class' => 'api\modules\v1\Module'
]
],
'components' => [
'user' => [
'identityClass' => 'common\models\User',
'enableAutoLogin' => false,
],
'log' => [
'traceLevel' => YII_DEBUG ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'urlManager' => [
'enablePrettyUrl' => true,
'enableStrictParsing' => true,
'showScriptName' => false,
'rules' => [
[
'class' => 'yii\rest\UrlRule',
'controller' => 'v1/country',
'tokens' => [
'{id}' => '<id:\\w+>'
]
]
],
]
],
'params' => $params,
];
Here is the model Country
<?php
namespace api\modules\v1\models;
use yii\db\ActiveRecord;
/**
* Country Model
*
* #author Budi Irawan <deerawan#gmail.com>
*/
class Country extends ActiveRecord
{
/**
* #inheritdoc
*/
public static function tableName()
{
return 'country';
}
/**
* We use the primary function because we don't use integer auto increment as a primary key.
* #inheritdoc
*/
public static function primaryKey()
{
return ['code'];
}
/**
* To let Yii know what fields exist on the table.
* Define rules for validation
*/
public function rules()
{
return [
[['code', 'name', 'population'], 'required']
];
}
}
I still get the same error while accessing it through http://localhost/yii2-api/api/v1/countries.

Answer 1

According to tutorial you have to use url :
http://localhost/yii2-api/api/web/v1/countries
Instead of
http://localhost/yii2-api/api/v1/countries

Answer 2

In my case,
the mysql table had compound primary key (made by mistake),
and only GET /v1/othertable/1 failed with this error, while other routes are working.
When I sorted that indexes through PhpMyAdmin it started to work.
