There was an error on the Joomla VirtueMart website. What to do?

Question

Joomla

An error has occurred. I don't understand what's the matter? Everything was fine, I did not climb into the code, did not change anything. The error itself:
Notice
: Undefined property: stdClass::$id in
/home/eratniks/mob.eratnikstudio.by/components/com_virtuemart/router.php
on line
1139

on line

What could it be? How to fix it?
