unable to create the rollup node

[uneuro]

Hi, trying to run a node but in docker logs I got this on the unichain-nod-op-node-1:

I did docker compose with all defaults, under up to date manjaro + docker Engine: 27.2.0 + Compose: v2.29.2-desktop.2

Ok I think I need to replace in .env files this setting: https://your.sepolia.beacon.node/endpoint-here with a full ETH node RPC

You need to edit Edit OP_NODE_L1_ETH_RPC and OP_NODE_L1_BEACON

You can find RPC and BEACON here : https://ethereum-sepolia.publicnode.com/?sepolia

You need an RPC, try to find a good one and replace these values on those files mentioned :

OP_NODE_L1_ETH_RPC and OP_NODE_L1_BEACON

These should be different but just for testing try it with the same.

I do have a full tutorial here : https://github.com/0xAJPanda/unichain-node

I hope it helps...

Hey all, I have two questions:

1. ShouId I be using ETH Sepolia or OPT Sepolia?
2. I'm using Alchemy and there's no Beacon API to be found for either ETH or OPT. What to do?
