p2p sync: "sanity check error: can not verify hash in block header for block number: 122549"

[eliotstock]

Testing with a build from source, pulled from release v0.12.2, I cannot begin to sync.

I used the snapshot from the README (https://juno-snapshots.nethermind.dev/files/sepolia/latest).

I'm starting Juno with:

./build/juno \
--db-path /data/juno/sepolia \
--http-port 6060 \
--eth-node wss://eth-sepolia.g.alchemy.com/v2/REMOVED_API_KEY \
--log-level DEBUG \
--network=sepolia \
--p2p \
--p2p-peers=/ip4/35.231.95.227/tcp/7777/p2p/12D3KooWNKz9BJmyWVFUnod6SQYLG4dYZNhs3GrMpiot63Y1DLYS

I'm seeing a lot of this, straight away:
