yii\base\ErrorException: Uninitialized string offset: 0

[savinpaul]

Hi ,

I got an issue in yii2 codeception functional test. I tried to add functional test for my login page. It works fine for the empty condition and wrong condition, but for success condition I got the above error. Below is the full output. If I remove the success condition it works fine.

Codeception PHP Testing Framework v2.0.3
Powered by PHPUnit 4.1.4 by Sebastian Bergmann.

How is your asset bundle class defined? The error indicates you have an invalid js property in your asset bundle class.

Thank You for your reply. Sorry for the late reply. Here is my AppAsset class which extends AssetBundle class.

namespace frontend\assets;
use yii\web\AssetBundle;

class AppAsset extends AssetBundle
{
    public $basePath = '@webroot';
    public $baseUrl = '@web';
    public $css = [
        'css/site.css',
         'css/bootstrap.css',

What is at: /var/www/html/portalv2/portalv2_base/frontend/views/layouts/main_login.php:102

[savinpaul]

Body ends at main_login.php 102

endBody(); ?>

Run codecept build command after including PHPBrowser as a module in functional.suite.yml and try again.

[qiangxue]

I can't tell how this would cause the error. Did you configure assetManager in your app config? If so, what is it? Did you use any other asset bundles? What are they?

[savinpaul]

Hi ,
This is working well now. I have just enabled PhpBrowser in functional.suite.yml file as suggested by @jitheshborgia . Problem seems to be solved. Thanks to all.
