Issue Description

Hi everyone!
I'm learning to create my own L2 rollup testnet by following the tutorials.
I encountered some Op-deployer issues but managed to fix them thanks to jsvisa.
Now I'm working on initializing and starting op-geth.

op-geth logs

ecotone upgrade scheduled but no beacon endpoint is configured

https://docs.optimism.io/operators/node-operators/configuration/consensus-config#l1beacon

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

[Guan21]

@imtipi
Thank you for your answer.
It seems that alchemy also provides the beacon endpoint. Is that correct?

[imtipi]

@imtipi Thank you for your answer. It seems that alchemy also provides the beacon endpoint. Is that correct?

not sure,because /eth/v1/beacon/blob_sidecars/head not works in alchemy

https://www.quicknode.com/docs/ethereum/eth-v1-beacon-blob_sidecars-id

[Guan21]

@imtipi
OK, I see.
I have already set L1_RPC_URL using Alchemy.
If I set l1.beacon using QuickNode, does this mean I need to change my L1_RPC_URL to one created by QuickNode?

[imtipi]

@imtipi OK, I see. I have already set L1_RPC_URL using Alchemy. If I set l1.beacon using QuickNode, does this mean I need to change my L1_RPC_URL to one created by QuickNode?

doesn't need to be the same

@Guan21 I am also trying to setup an op-stack roll up for testnet using tutorials/chain branch and ran in the same issue added this flag as well #741 (comment) but it resulted in unknown flag error. so can you help me with the changes you have made and what versions of release you have used.

[imtipi]

--l1.beacon introduced in op-node v1.5.0, so I suggest trying a previous version like v1.4.3
