Unable to validate "27C" as chunk length header

[mdrost]

I don't know how to reproduce problem using only this library, but with WyriHaximus/react-guzzle-psr7 this code

<?php

require_once __DIR__ . '/vendor/autoload.php';

$loop = React\EventLoop\Factory::create();
$handler = new WyriHaximus\React\GuzzlePsr7\HttpClientAdapter($loop);
$client = new GuzzleHttp\Client([
    'handler' => GuzzleHttp\HandlerStack::create($handler),
]);

$request = new GuzzleHttp\Psr7\Request('GET', 'https://wizzair.com/');
$promise = $client->sendAsync($request)->then(function (Psr\Http\Message\ResponseInterface $response) {
    echo (string)$response->getBody();
});

$promise->wait();

produces

Hey thank you for reporting your issue. By the looks of it you're calling $promise->wait(); which forces the promise to resolve and blocks the loop. Running the loop the normal way, $loop->run(); will ensure the loop isn't blocked. I've just tried your URL with this example and had no issues what so ever: https://github.com/WyriHaximus/react-guzzle-psr7/blob/master/examples/basic.php

This should resolve your issue, so I'll close this for now. If you feel this problem persists, please report back and we can reopen this 👍

With other url's my code is not blocking.
When I change my code to

<?php

require_once __DIR__ . '/vendor/autoload.php';

$loop = React\EventLoop\Factory::create();
$handler = new WyriHaximus\React\GuzzlePsr7\HttpClientAdapter($loop);
$client = new GuzzleHttp\Client([
    'handler' => GuzzleHttp\HandlerStack::create($handler),
]);

$request = new GuzzleHttp\Psr7\Request('GET', 'https://wizzair.com/');
$promise = $client->sendAsync($request)->then(function (Psr\Http\Message\ResponseInterface $response) {
    echo (string)$response->getBody();
}, function (Exception $e) {
    echo $e;
});

$loop->run();

I get

Other url's works, just wizzair is somehow special.

Your example works fine until I change url to https://wizzair.com/ . Then i get An error occured in the response.

I fix that #77
