WordPress caught an error with one of your plugins, Slimstat Analytics

I just received an error message from WordPress. I changed our site address in the messages below to xxx:

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Slimstat Analytics.

First, visit your website (https://xxx.com/) and check for any visible issues. Next, visit the page where the error was caught (https://xxx.com/wp-login.php?action=lostpassword&redirect_to=https://xxx.com/forums/reply/6894/?ld-resetpw=true) and check for any visible issues.

slimstat did not show anyone accessing that page. i accessed the page without any errors and my access did show up in slimstat.
