Complex object is completely unreadable after upgrade to SDK RC-9

[cthulhu-rider]

• see Complex object is not readable through non-container node #2447

i made same actions but with later NeoFS revision, but the result is completely different

all nodes respond with

rpc error: read object header: status: code = 2049 message = object not found

as opposed to access problem from another issue, here node can't even reach the fact that requested object is complex (virtual). I guess the problem may be in status codes and/or SDK client errors

Versions

• neofs-cli v0.37.0
• neofs-node >= 18e3f68106f4e9d5f5ecda8f4b1caef74358be55 (not yet released)

i have not seen no split info on parent object error in log before, can be caused by problems with slicing? @carpawell

[cthulhu-rider]

i guess i found the reason: parent header contains split ID (slicing mistake) while it shouldn't. It's not obvious why metabase fails due to this, need to explore separately. If node considers such objects as problem, then it must deny them on PUT stage. I'll create an issue

• current bug should be fixed after slicer: Do not write split ID into parent header neofs-sdk-go#474

[roman-khimov]

Do I understand correctly that we can't release node with SDK RC9 and we definitely need RC10 for everything to work correctly?

[roman-khimov]

Fixed by #2470?
