 * Hi there,
 * A site we manage has been infrequently receiving these error messages from the
   POST SMTP plugin:
 * > You are getting this message because an error was detected while delivering
   > your email.
   > For the domain: [https://waringsbakery.co.uk](https://waringsbakery.co.uk/)
   > The log to paste when you open a support issue:WpOrg\Requests\Transport\Curl::
   > request(): Argument [#3](https://studioteam.zendesk.com/agent/tickets/3) ($
   > data) must be of type array|string, boolean given
 * Checking the Email logs within the plugin, we cannot see where this is originating
   from (is it from a form on a page or an email from the WordPress/WooCommerce 
   etc..). Checking our server logs, we see this:

 * Any ideas on what this error message is?
 * Thank you

 * Hi [@sitebites](https://wordpress.org/support/users/sitebites/),

 * Can you share the diagnostic report so we can look into it and get back to you.
   Simply Go to the Post SMTP dashboard. You will see the Diagnostic Test under 
   the Troubleshooting Tab. Click [here](https://postmansmtp.com/documentation/others/how-to-get-diagnostic-test-report/)

 * Hi [@sitebites](https://wordpress.org/support/users/sitebites/) 
   I hope you are
   doing well.This is not an issue with Post SMTP, as Post SMTP is only sending 
   this alert email. The issue is likely with your website code or plugins. I recommend
   that you contact your developer to investigate the issue further.

 * Hi [@haseeb0001](https://wordpress.org/support/users/haseeb0001/) ,
 * Isn’t “PostmanWpMail.php” one of the files within your plugin ([see this screenshot with the error code](https://www.dropbox.com/scl/fi/0byyohugfwsihb1r42c5p/Screenshot_2023-09-27_at_10_01_33.jpg?rlkey=horo4p6k3n4ptrdxww6azpvjj&dl=0));
   that’s why we though it best to contact you as the error message dedicated to
   open a support issue?
