Problems after migrating to the Fusaka network. Errors in the op-node

[neodiz]

Bug Description
I have a network connected to Sepolia. Transactions are stuck in pending mode. Restarting op-batcher temporarily solves the problem. I also see an error in the op-node logs. Op-batcher also has a warning message

Steps to Reproduce
The problem started after updating Kusaka
Expected behavior

t=2025-10-23T07:55:09+0000 lvl=warn msg="Engine temporary error" err="derivation failed: temp: failed to fetch blobs: expected 2 blobs but got 8", I'm not sure if this is a issue of the beacon node, could you please provide more information about the L1 beacon node, which client and the version

[neodiz]

I have 2 node.

1. connected now
   • prysm (prysm-beacon-chain:v6.1.2)
   • geth ( Geth/v1.16.6-unstable-116c9167-20251022/linux-amd64/go1.24.9)
2. backup node

• lighhouse (Lighthouse v8.0.0-rc.0-e5b4983)
• erigon (erigon version 3.2.0-3418e071)
