Yii2 beginner. Display REST exception handling

In my controller, I extend the Controller class instead of ActiveController

I have a simple actionIndex() method:

public function actionIndex(){

    return json_encode(["text" => "some text"]);
}

When I access the certain route in browser, in the debugger, I see that this function is executing (the breakpoint stops inside the function), but I get 500 status code (Internal server error). How can I find the cause of the error? I have implemented the actionError() method, but it is not executing. 

    public function actionError() {
    $exception = Yii::$app->errorHandler->exception;
    if ($exception !== null) {
        return $this->render('error', ['exception' => $exception]);
    }
}

If I put the logic of the actionError() method in the actionIndex(), the $exception variable is null

The only output I get is:

{
name: "PHP Warning",
message: "Expected array for frame 0",
code: 2,
type: "yii\base\ErrorException",
file: "Unknown",
line: 0,
stack-trace: []
}

but it's warning, not error. May this cause the status code 500?

How can I get the error? Thanks!

According to this thread https://github.com/yiisoft/yii2/issues/11120 this is related to Xdebug for Yii 2 < 2.0.9. When handling an exception, XDebug modifies the exception and Yii2 was not able to handle it correctly.

So several possible solutions here

  • The best idea is to update Yii2 to a version >= 2.0.9
  • Also you sould correct the source of the exception (the warning). It is never a good idea to have warnings. It can hide some more issues.
  • And as a workaround, you can disable XDebug. It is very useful during development but must be disabled in production in all cases.

Don't know about your error, but there is generally no need to return a response as json encoded. Yii checks the Accept-header of the request and adjust output accordingly. In your case I would just use: 

public function actionIndex()
{
    return ["text" => "some text"];
}

Possibly it might also solve your error...
