Node API health check using a method not found by the Grin node.

[syntaxjak]

get_chain_tip ("get_tip") is not known by the grin node, causing the program to error out on a healthy node.

mwixnet.rs
...

if let Err(e) = rt_handle.block_on(node.async_get_chain_tip()) {
	eprintln!("Node communication failure. Is node listening?");
	return Err(e.into());
};

This is the corresponding function with the "get_tip" method that is not found by the grin node. Maybe change to get_status?

Node.rs

async fn async_get_chain_tip(&self) -> Result<(u64, Hash), NodeError> {
	let params = json!([]);
	let tip_json = self
		.async_send_request::<serde_json::Value>("get_tip", &params)
		.await?;
	let tip =
		serde_json::from_value::<Tip>(tip_json).map_err(NodeError::DecodeResponseError)?;

	Ok((
		tip.height,
		Hash::from_hex(tip.last_block_pushed.as_str()).unwrap(),
	))
}
