PHP Deprecated / PHP 8.2 / ReturnTypeWillChange

[FlipZoomMedia]

Thank you for the great module. Under PHP 8.2 I get a deprecation message in debug mode.

PHP Deprecated: Return type of ProcessWire\Geocoder::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in [/site/modules/FieldtypeGeocoder/Geocoder.php:119]

I'm not quite sure if this is the right solution, but if I define the retun type array for the function jsonSerialize() in line 119, I no longer get a message. But I don't know what side effects this could have.

/**
 * @return array|mixed
 */
public function jsonSerialize(): array {
    return $this->getArray();
}
