Hi,
LibreNMS was working fine, and now without changing anything when I click on any of the devices to view the “overview” tab, I get:
# Whoops, looks like something went wrong. Check your librenms.log
In that log I see:
[2021-10-20 00:58:53] production.ERROR: Method Illuminate\View\View::__toString() must not throw an exception, caught Illuminate\View\ViewException: Argument 1 passed to League\CommonMark\Converter::convertToHtml() must be of the type string, null given, called in /ssd/librenms/vendor/laravel/framework/src/Illuminate/Support/Str.php on line 394 (View: /ssd/librenms/app/Plugins/ExamplePlugin/resources/views/device-overview.blade.php) {"userId":1,"exception":"[object] (Symfony\\Component\\ErrorHandler\\Error\\FatalError(code: 0): Method Illuminate\\View\\View::__toString() must not throw an exception, caught Illuminate\\View\\ViewException: Argument 1 passed to League\\CommonMark\\Converter::convertToHtml() must be of the type string, null given, called in /ssd/librenms/vendor/laravel/framework/src/Illuminate/Support/Str.php on line 394 (View: /ssd/librenms/app/Plugins/ExamplePlugin/resources/views/device-overview.blade.php) at /ssd/librenms/includes/html/pages/device/overview.inc.php:0) [stacktrace] #0 {main} "}

Polling still seems to be working fine…and the graphs are all updating.
Any ideas…??
