rpc error: read object header via client: received header mismatches ID

Possible Solution

Need to find the root cause, maybe something like #3359 fix is relevant here as well.

Steps to Reproduce (for bugs)

Above.

Context

Mainnet.

Regression

Yes (ID wasn't checked before 0.48.0), but it shouldn't be. This mismatch suggests that header format has changed in some incompatible way. Or it was calculated incorrectly at some point and stored this way (which is rather strange as well).

Your Environment

Version used: 0.48.1
Server setup and configuration: mainnet.

@roman-khimov commented on GitHub (Aug 7, 2025):

It's a two-byte diff at 9.1.3 which is session token lifetime. It's either completely missing (reencoded with current code) or present with empty contents (old header, 1a00). So it's very close to https://github.com/nspcc-dev/neofs-sdk-go/pull/715 problem. Looks like we need to adjust the encoder here as well.
