Uncaught TypeError: Argument 3 passed to Slim\\Handlers\\ApiError

[sjozsef]

The problem is that PHP \Error objects gets passed to \Slim\Handlers\ApiError::__invoke() method, wich is assuming \Exceptions instead of \Errors.

To reproduce that bug, try to create a todo with invalid json format:

curl "https://192.168.50.52/todos" --request POST --include --insecure --header "Authorization: Bearer $TOKEN" --header "Content-Type: application/json" --data "{ 'title': 'Test the API', 'order': 10 }"

Hotfix:

Comment out that lines in config/handlers.php:

$container["phpErrorHandler"] = function ($container) {
    return $container["errorHandler"];
};

If you pass an Accept: application/json header to your requests, you'll get simple json errors via the built-in Slim error handler.

If you want to handle PHP Errors as API Problems (like ApiError handler does), you have to implement a new error handler based on the built-in Slim PhpError class.

Should be fixed with 9f810e0.

Please help.

As long as no errors in the program everything works fine. But when there is an error it shows this message and not handling it properly.

Seems like the error handling is throwing errors. Need a quick fix.

@pdrappo are you running PHP 5 or 7? I try to reproduce this.

[pdrappo]

@tuupola Mike, i'm using PHP 7 on CLI mode when i'm developing.

[ganesh35]

I am using PHP Version 7.1.1

Quick fix for Php7 would be replacing \Exception with \Throwable for:

slim-api-skeleton/src/Slim/Handlers/ApiError.php

Line 37 in f5231bc

public function __invoke(Request $request, Response $response, \Exception $exception)
