Originally created by @cthulhu-rider on GitHub (Jun 23, 2025).

Current Behavior

fail occured once

Expected Behavior

either always pass or fail

Possible Solution

perhaps the problem is on NeoFS side. Need to explore

i also noticed that in failure case same OID occured in different suites. In such cases, a read-delete race is usually suspected

Context

https://github.com/nspcc-dev/neofs-node/pull/3406

Regression

maybe

@roman-khimov seems like a bug in rest gw for me, there are 2 objects with same attribute - 'Writer': 'Leo Tolstoy'. Test removes one, then tries to get a second object by this attribute but gets an error status: code = 2052 message = object already removed. get by id works ok. Not sure why it reproduced once, maybe some caching issue?

It looks like cache or search returning an old ID which is then unavailable. Depending on specifics it's either a feature or a bug. @evgeniiz321, can you look into logs to check what really happens there?
