[OP Stack Deployment] Incorrect L1 Genesis Block Hash Error When Starting op-node

Issue Description

I'm following the official Optimism OP Stack "Creating your own L2 rollup testnet" tutorial and running op-node v1.12.0. After deploying contracts and generating config files with op-deployer and successfully running op-geth, I attempt to start my node with the following command:

./bin/op-node \ --l2=http://localhost:8551 \ --l2.jwt-secret=./jwt.txt \ --sequencer.enabled \ --sequencer.l1-confs=5 \ --verifier.l1-confs=4 \ --rollup.config=./rollup.json \ --rpc.addr=0.0.0.0 \ --rpc.port=8547 \ --p2p.disable \ --rpc.enable-admin \ --p2p.sequencer.key=$GS_SEQUENCER_PRIVATE_KEY \ --l1=$L1_RPC_URL \ --l1.rpckind=$L1_RPC_KIND \ --l1.beacon="https://ethereum-sepolia-beacon-api.publicnode.com/"

Steps already taken:

• Fully redeployed all contracts using op-deployer apply with the same $L1_RPC_URL as used in the node command.
• Regenerated both genesis.json and rollup.json.
• Re-initialized and restarted both op-geth and op-node with the new configs.
• Confirmed that $L1_RPC_URL is consistent and correctly set in the environment.

Despite this, op-node still reports a mismatch between the actual L1 genesis block hash and the expected one from the rollup config.

Looking for guidance on resolving this persistent genesis hash mismatch when following the official OP Stack deployment flow and using a public Sepolia endpoint.

please provide your rollup.json try to relace the expected 0xebd4d8820e2f0a63ef4630456ee9f23a0d76f43dcf28c049e987e9a0fb325885" with the rollup.json's l1 block hash frist,

--rpc.port=8547 you have set 8547 here Default is 9545.

Thank you, op-node, op-geth, and op-batcher seem to be running fine. Op-proposer is also running; however, I am running into this error, after funding the L1 Proposer address with ETH:

This is what I am running:

From state.json: "disputeGameFactoryProxyAddress": "0x217b67859f3dae392370391fb38a51a728b49e8d",

This discussion indicates to use game-factory-address, not l2oo: #798

Please restart op-proposer, and then intercept the beginning log to see if there is a successful published.
We found that even if the publision is successful, similar warnings will still appear. Let us rule out this factor through the beginning of the log.

No successful publications, I checked the L1 contract as well and there have been no games created on the disputegamefactoryproxy. Will restart the proposer again and report back.
