Undefined array key "allowOverride"

[sklngr]

Bug Report

Current Behavior
Error message undefined array key "allowOverride" is displayed when a URL is called with override values e.g. tx_ttaddress_listview[override][categories]=1, although the content element has allowOverride not enabled.
Documentation

tt_address/Documentation/Administration/Changelog/v/4-2-0.rst

Lines 37 to 40 in a88e763

	<f:link.page
	additionalParams="{tx_ttaddress_listview:{override:{categories: 1}}}">
	Category 1
	</f:link.page>

Expected behavior/output
no error message should be displayed, instead an address list matching the defined (not override) values should be displayed

Environment

• TYPO3 version(s): 12.4.38 / 12.4.43
• tt_address version: 9.1.0
• Is your TYPO3 installation set up with Composer (Composer Mode): no

Possible Solution
The error is caused by line

tt_address/Classes/Controller/AddressController.php

Line 84 in a88e763

if (!empty($override) && $this->settings['allowOverride']) {

This line should be changed to:
if (!empty($override) && (int) ($this->settings['allowOverride'] ?? 0) === 1) {
