Fatal error while sending exception

Hi
I have found an issue in code while sending exception.
File: fluent-smtp/app/Services/Mailer/BaseHandler.php
Line: 273
Code: throw new \PHPMailer\PHPMailer\Exception($message, $code);

This gives fatal error while attempting to send email, and if it get an error message from the smtp host.

Exception should take one input argument whereas you are sending two arguments “message” and “code” in exception.
Can you please update code and push a new update for the plugin as this is a critical issue when smtp server return and error it generate internal server error 500.

to be precise here is the error

PHP Fatal error:  Uncaught Error: Wrong parameters for PHPMailer\PHPMailer\Exception([string $message [, long $code [, Throwable $previous = NULL]]]) in /home/xyz/public_html/wp-content/plugins/fluent-smtp/app/Services/Mailer/BaseHandler.php:273
