Getting Error Undefined array key

[yhchen0]

I want get user info, so I try use:

$targetUrl = "https://graph.facebook.com/v11.0/oauth/access_token";
$getAccessTokenRes = Http::get($targetUrl, [
    'client_id' => $client_id,
    'client_secret' => $client_secret,
    'redirect_uri' => $redirectURL,
    'code' => $code
]);
$accessToken = json_decode($getAccessTokenRes->body())->access_token;
$accessUserInfo = $fb->get('/me', $accessToken); //Get Error

Error message is: ErrorException Undefined array key 1
After tracing, I found that the error came from
vendor/facebook/graph-sdk/src/Facebook/Http/GraphRawResponse.php:109

public function setHttpResponseCodeFromHeader($rawResponseHeader)
{
    preg_match('|HTTP/\d\.\d\s+(\d+)\s+.*|', $rawResponseHeader, $match); // $rawResponseHeader = 'HTTP/2 200'
    $this->httpResponseCode = (int)$match[1];
}

I try to use var_dump print $rawResponseHeader value, the content is HTTP/2 200
I think it is because the content does not match the pattern of preg_match, which causes the error.

I am very confused, because I tried to create two Facebook applications, the first time was successful, but the second application encountered this problem.

setHttpResponseCodeFromHeader it is very poorly designed! It is not compatible with HTTP/2
Does anyone knows a fork with this fixed?

Hello,

This could be fixed by changing line 107 to

preg_match('/HTTP\/\d(?:\.\d)?\s+(\d+)\s+/',$rawResponseHeader, $match);

Would need an official fix as editing the file is not recommended
