How to use 2 and 402757 in snippet parameter in MODX if the site is on a subdomain?

Question

MODX

Hi all.
MODX Revo 2.3.2.
Website on a subdomain
Strange bug: in the snippet parameter (pdoResources, getImageList, etc.) I can't use the parameter &parents=`2`. The snippet page is not saved. The error log is empty. If you specify &parents=`0`, i.e. specific value - everything is ok.
Probably the problem is actually that the parser cannot trace the path if I use 2 in the snippet. But I have no idea how to decide.
