Still sending Error alerts

[bh2smith]

Somehow, this code block (even though it is just a print statement) is still appears as an error in our alerts channel.

I have also checked with devops to see if they have some of their own triggers for such alerts (like any string containing "failed" or something).

etherbalance/src/main.rs

Lines 151 to 161 in c13d061

	Err(err) => {
	success_metric
	.with_label_values(&["failure", &format!("{:#x}", params.address)])
	.inc();
	println!(
	"failed to get balance for address {} token {}: {}",
	&format!("{:#x}", params.address),
	params.token_name,
	err
	);
	}
