Issues advancing OP Base

[mattsse]

Describe the feature

newPayloadsV2 are currently being rejected with missing withdrawals after canyon update:

"{\"jsonrpc\":\"2.0\",\"error\":{\"code\":-32602,\"message\":\"Invalid params\",\"data\":{\"err\":\"withdrawals pre-Shanghai\"}},\

The bug is that OP canyon adds support for shanghai https://eips.ethereum.org/EIPS/eip-4895

https://blog.oplabs.co/canyon-hardfork/

and we reject them here:

reth/crates/rpc/rpc-engine-api/src/engine_api.rs

Lines 121 to 125 in 8686e97

	validate_version_specific_fields(
	&self.inner.chain_spec,
	EngineApiMessageVersion::V2,
	&payload_or_attrs,
	)?;

more specifically:

reth/crates/node-api/src/engine/mod.rs

Lines 219 to 222 in 8686e97

	EngineApiMessageVersion::V2 | EngineApiMessageVersion::V3 => {
	if is_shanghai && !has_withdrawals {
	return Err(AttributesValidationError::NoWithdrawalsPostShanghai)
	}

because we only check for Hardfork::Shanghai:

reth/crates/node-api/src/engine/mod.rs

Line 208 in 8686e97

let is_shanghai = chain_spec.fork(Hardfork::Shanghai).active_at_timestamp(timestamp);
