PHP warning for Guzzle

Hello!

Any plans to address this PHP warning, now that PHP 7.3 is out?

PHP Warning: count(): Parameter must be an array or an object that implements Countable in /home/redacted/public_html/wp-content/plugins/constant-contact-api/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php on line 67

Here’s the fix: https://github.com/guzzle/guzzle/issues/1973#issuecomment-396278571
