Description

In commit 46a66956 the lines 114-118 of AmpHttpClient.php were changed to use the match() expression instead of switch-case:

-            switch ((float) $options['http_version']) {
-                case 1.0: $request->setProtocolVersions(['1.0']); break;
-                case 1.1: $request->setProtocolVersions(['1.1', '1.0']); break;
-                default: $request->setProtocolVersions(['2', '1.1', '1.0']); break;
-            }
+            $request->setProtocolVersions(match ((float) $options['http_version']) {
+                1.0 => ['1.0'],
+                1.1 => $request->setProtocolVersions(['1.1', '1.0']),
+                default => ['2', '1.1', '1.0'],
+            });

If the provided $options['http_version'] is 1.1, the code will call $request->setProtocolVersions() inside the match(), unlike with 1.0 and the default case. The match will use the return value of setProtocolVersions(), but since it's a void function, the return value is null.

This then results in a TypeError as setProtocolVersions() (the "outer" one) expects an array.

How to reproduce

// First, run "composer require symfony/http-client" and " composer require amphp/http-client"
// Then, execute this file:
require_once __DIR__.'/vendor/autoload.php';
use Symfony\Component\HttpClient\AmpHttpClient;

$client = new AmpHttpClient();

$response = $client->request(
    'GET',
    'http://example.com',
    [
      'http_version' => '1.1'
    ]
);

// The script will fail with the TypeError and never reach this point
var_dump($response->getStatusCode());

Solution

Change line 116 to match line 115 & 117:

$request->setProtocolVersions(match ((float) $options['http_version']) {
    1.0 => ['1.0'],
-   1.1 => $request->setProtocolVersions(['1.1', '1.0']),
+   1.1 => ['1.1', '1.0'],
    default => ['2', '1.1', '1.0'],
});
