Poll metrics Error in metrics dashboard during node start

[imnik11]

What happened?

Maybe the metrics polling process started before the transaction_validation and it got empty so, it is unable to poll metrics

What is expected ?

It expected to start normally and give the archethic_mining_full_transaction_validation_duration => val , similarly others metrics etc

I think the issue is due to the use Enum.reduce/2 instead of Enum.reduce/3 as with the first one not accumulator is given.
Then if there are not nodes yet available or authorized during the startup when the polling is initiated, Enum.reduce/2 crashes if the list is empty. Hence the accumulator will help.
But another improvement will be to start the poller only when the local is completely initialized.
