The @EVAL prefix is deprecated in MODX3. Do you use one of these in your TV?

@EVAL return $modx->runSnippet('pdoResources', [    'parents' => 67,    'sortby' => '{"menuindex":"ASC"}',    'limit' => 0,    'tpl' => '@INLINE [[+pagetitle]]==[[+id]]',    'outputSeparator' => '||']);

Convert it to this using https://wtools.io/convert-php-array-to-json:

@SNIPPET pdoResources {
    "parents": 67,
    "sortby": "{\"menuindex\":\"ASC\"}",
    "limit": 0,
    "tpl": "@INLINE [[+pagetitle]]==[[+id]]",
    "outputSeparator": "||"
}
