Issue Description

I am trying to create a Layer 2 (L2) rollup using op-node, following the tutorials provided in the Creating your own rollup testnet Docs . However, I am encountering an error when executing the following command:

On Step: Start op-geth

./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 \
  --p2p.disable \
  --rpc.enable-admin \
  --p2p.sequencer.key=$GS_SEQUENCER_PRIVATE_KEY \
  --l1=$L1_RPC_URL \  #providing Alchemy API key
  --l1.rpckind=$L1_RPC_KIND  # providing Alchemy

Error Message:

Additional Information

I have followed the steps provided in the linked documentation, and everything went smoothly up to the contracts deployment on L1. This is the step where I am currently facing issues.

if you use tutorials/chain you shouldn't need to set l1 beacon

but if you want to try the latest OP Stack,then go on
https://docs.optimism.io/operators/node-operators/configuration/consensus-config#l1beacon

--l1.beacon= add this,and add any l1 rpc that provides /eth/v1/beacon/blob_sidecars method,for me I use quicknode

I am trying to deploy a Layer2 testnet on Binance Smart Chain testnet. But I can not find beacon api for BSC. How can I get one ?
