[OP Stack Deployment] Fail to read rollup.json for L3 chain on base

Issue Description

I am trying to deploy local node for a L3 chain based on OP stack + Base settlement + EigenDA. It's build on conduit platform. I got rollup config, genesis json, contracts.json and also enabled external nodes. I successfully init op-geth but fail to start op-node with rollup.json. I can't get any useful information from the error logs. I had tried to change the file permission, move to project root folder and try to break the json file. When I break the json file, it can show what data field is missing so I assume permission are setup correctly and op-node can read the rollup.json file successfully.

Logs

Same thing , i have the same error .
op-node_1 | {"t":"2026-01-09T12:16:26.714460856Z","lvl":"crit","msg":"Application failed","message":"failed to setup: unable to create the rollup node config: failed to read chain spec: open : no such file or directory"}

I have all files : jwt.txtz,genesis.json and rollup.json

Please if you find a solution help me .

i resolve , you need to pass this flag "--rollup.l1-chain-config" to op-node :
this file is the genesis file from your blockchain , im using a besu hyperledger so mine its not on Sepolia or Ethereum Mainet so i need to configure this file .
rollup.l1-chain-config
"Path to .json file with the chain configuration for the L1, either in the direct format or genesis.json format (i.e. embedded under the .config property). Not necessary / will be ignored if using Ethereum mainnet or Sepolia as an L1."
the flag to bee added to docker-compose file or just pass this comand if you used op-node from source:
- "--rollup.l1-chain-config=/workspace/genesis_my_zero_gas_teste_genesis.json"

@vadimchilinciuc Thank you for your answer. I am looking for anyway to get the Big L2 chain's genesis file like base, base sepolia ? Seems like chain operator is no longer provide the genesis.json file and it is no longer needed to run the L2 chain for the super chain.
