	// TODO (PLA-333): at the moment the latest version of `web3` crate doesn't have `Finalized` variant in `BlockNumber`.
	// However, it's already added in github repo and probably will be included in the next released version.
	// Scope of PLA-333 includes forking/using crate directly from github, after that we will be able to change
	// type of `block_id` from `String` to `BlockId` and use `self.web3.eth().block(block_id)`.
	async fn block(
	&self,
	block_id: String,
	component: &'static str,
	) -> Result<Option<Block<H256>>, Error> {
	COUNTERS.call[&(Method::Block, component)].inc();
	let latency = LATENCIES.direct[&Method::Block].start();
	let block = CallFuture::new(
	self.web3
	.transport()
	.execute("eth_getBlockByNumber", vec![block_id.into(), false.into()]),
	)
	.await?;
	latency.observe();
	Ok(block)
	}

This PR fixes the TODO.

The web3 crate being used inside the project was updated to version 0.19.0 inside core/lib/basic_types/Cargo.toml in commit 829ef50.

The web3 crate now supports BlockNumber::Finalized.
