Our website has a front-end event submission form (menu item type Create JEvents). When users try to submit an event, they get this error:

0 - Argument 1 passed to Joomla\Utilities\ArrayHelper::toObject() must be of the type array, null given, called in /home/shelburnefalls/public_html/plugins/finder/jevents/jevents.php on line 366

This sounds similar to the issue in another forum post:
https://www.jevents.net/discussions/error-saving-event-as-status-trashed-after-3-4-41-upgrade

I'm running JEvents 3.4.41 and Joomla 3.7.5. Do you have any suggestions for how to fix this issue?

Thanks very much for your help!
