Undefined array key "getResourcesSnippet"

Just updated Collections and getSelections breaks the site

[2023-06-12 15:43:35] (ERROR @ /www/core/cache/includes/elements/modx/revolution/modsnippet/33.include.cache.php : 91) PHP warning: Undefined array key "getResourcesSnippet"

[toro-terminator]

It was something else completely breaking my site but this error stops when I change line 91

//$properties['parents'] = ($properties['getResourcesSnippet'] == 'pdoResources') ? 0 : -1;
$properties['parents'] = -1;
