I guess you get this internal warning in PHP:
Warning: Undefined array key "HTTP_ORIGIN"
This warning will be sent by PHP before the Slim$response
is getting handled.
Please note that theHTTP_ORIGIN
header is not always present, and it is not good practice to rely on this key. Instead it's better to check the domain and send a*
when it's valid.
This prevent this warning try this:
$httpOrigin = $request->getServerParams()['HTTP_ORIGIN'] ?? '';
if($httpOrigin) {
$response = $response->withHeader('Access-Control-Allow-Origin', $httpOrigin);
}
return $response->withHeader('Content-Type', 'text/plain')
->withHeader('X-Error-Message', $message)
->withStatus(403);
