PHP Fatal error: Uncaught exception 'http\Exception\UnexpectedValueException' with message 'Failed to locate "(null)" client request handler'

I always get that when trying to use any pecl_http 2 code... Same if I explicitly pass curl as handler.
Can't seem to find anything on that anywhere, really annoying as this has been made the default http package for PHP on Ubuntu (that I know off).

Install libcurlX-Y-dev where X is 3 or 4 and Y is openssl or gnutls.
See also https://bugs.php.net/bug.php?id=67316

Y might be any SSL library, like e.g. NSS, too.

I'm trying to disable SSL peer verification with
$r = new http\Client\Request("POST", XML_ENDPOINT, NULL, $body);
$r->setSslOptions([
'verifyhost' => false,
'verifypeer' => false,
]);
but I'm not having any success, can someone suggest how to proceed?

@fpischedda
2 years later... the method return client so you have to write "$r = $r->setSsl......."
Php is a very very good language... ironic.
