6. Start zkSync node ./bin/zk server

Blockers

I'm experiencing the below blocker. Tried using a different RPC endpoint, but still failed:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: EthereumGateway(Rpc(Error { code: ServerError(-32000), message: "FeeHistory user block count 1024 higher than 100", data: None }))', /zksync-era/core/bin/zksync_core/src/l1_gas_price/singleton.rs:27:22

@crypto-matto from your error, it seems it is caused to cronos rpc endpoint base_fee_history limitation which can only have a max block count value to 100

Can you modify the config or the code to make it works?
