Warning: Undefined property: stdClass::$type in httpdocs/administrator/components/com_jevents/install.php on line 619

After updating Joomla from 3 to 4, I got several errors which have seen to mostly go away. However, on launching the JEvents Dashboard, it launches, but at the top I get these errors:

<strong>Warning: Undefined property: stdClass::$type in httpdocs/administrator/components/com_jevents/install.php on line 619

Warning: Undefined property: stdClass::$type in httpdocs/administrator/components/com_jevents/install.php on line 625

Warning: Undefined property: stdClass::$type in httpdocs/administrator/components/com_jevents/install.php on line 983</strong>

			$db->setQuery($sql);

			@$db->execute();

		}

625:

	if (array_key_exists("organizer", $cols) && strtoupper($cols['organizer']->type) !== "VARCHAR(500)")

		{

			$sql = "ALTER TABLE #__jevents_vevdetail MODIFY COLUMN organizer VARCHAR(500) NOT NULL default ''";

			$db->setQuery($sql);

			@$db->execute();

		}

983:

		if (array_key_exists("contact", $cols) && strtoupper($cols['contact']->type) !== "VARCHAR(500)")

		{

			$sql = "ALTER TABLE #__jevents_translation MODIFY COLUMN contact VARCHAR(500) NOT NULL default ''";

			$db->setQuery($sql);

			@$db->execute();

		}

Any ideas?

Thank you
