Problem with RPC connection

[swigsstaking]

I just launched my optimism node and I have this error in my op-node logs.

I connected it with one of our RCP Ethereum nodes using geth. This already works for other RPC uses and is therefore functional. Does anyone know if I need to change something?

So you're seeing that warning because you don't have --l1.rpckind configured on your op-node. Here's some supporting documentation. You'll find:

The kind of RPC provider, used to inform optimal transactions receipts fetching, and thus reduce costs. Valid options: alchemy, quicknode, infura, parity, nethermind, debug_geth, erigon, basic, any, standard. The default value is standard.

If you're running a geth node (with debug enabled), you can configure with debug_geth. This will speed up your receipt fetching and that will speed up your sync time.
