Also happens with link field inside e.g. a structure.

Summary

When no parents found, response is array, array is empty and we have empty check: https://github.com/getkirby/kirby/blob/4.4.0-rc.1/src/Panel/Json.php#L78-L80

Possible solutions

• Put site/tree/parents request in vue component into try/catch block
• Return a multidimensional array instead of flat array.

return [
  'data' => $parents
];

@afbora Makes sense, thanks for debugging. I think the 2nd solution sounds like the best way with our API.
