Did we specifically not returned any error here? If so I think this should be a warn instead of error

I think error is the right level here since this should never happen

Why dont we return the error?

Could go either way. The desire was not to treat this as fatal since it's only used to add an extra metric.

This is a bit hard to read, can we split this into two different variables?

I think this is fine for this PR since it's just copied from miner/worker.go
