Error on My Calendar Plugin

Can you tell me where it’s showing up, exactly? That’s a library that My Calendar uses; but I’d really need to know the callstack or at least how to reproduce it to have much idea.

If you can let me know what PHP version your site is running on, what WordPress version, and give me some information about where I might be able to reproduce this error, it would be much appreciated!

I am running PHP 8.1, I host at Kinsta. I got the error from Kinsta and and running current version of everything. It is happening on https://vibedancemadison.com

I don’t see it on your site anywhere; is there a specific location where I should look for it? Is it only visible when you’re logged in? Or is it something you received a notification about, but aren’t seeing present on the page?

Yes it’s something I received a notification about.
This is the message I received, as I posted in my original message.

PHP message: PHP Fatal error: Uncaught BadMethodCallException: There’s no value standard defined for enum Spatie\IcalendarGenerator\Enums\TimezoneEntryType, consider adding it in the docblock definition. in /www/vibedancemadisoncom_149/public/wp-content/plugins/my-calendar/vendor/spatie/enum/src/Enum.php:156

What I’ve learned about this is that it’s been fixed in the dependency, *but* the fix came along with requiring PHP 8. So I might have to make a fork of the dependency, since right now it would be premature to require PHP 8 for this plugin.
