How to reproduce error

Run below command on main

just run-client-native 22335001 <L1_RPC> <L1_NODE_RPC> <L2_RPC> <L2_NODE_RPC>

Fixed by

1. Updating batcher address

• For some reason base-sepolia's batcher address has changed
• Old address: 0x6cdebe940bc0f26850285caca097c11c33103e47 has not been posting since 15 days ago.
• New address: 0xfc56E7272EEBBBA5bC6c544e159483C4a38f8bA3

2. Picking a longer L1 head block

• For some reason, L1 head with + 30 blocks from L1 origin for base sepolia is too close, failing with EndOfSource.
• • 40 blocks was not working as well.
