cardano.node.Forge:Error

[adityatelidevara]

Once every couple of days I’m getting this error in the block producing node
cardano.node.Forge:Error:54] [2021-03-18 15:45:33.00 UTC] fromList [(“credentials”,String “Cardano”),(“val”,Object (fromList [(“kind”,String “TraceNoLedgerView”),(“slot”,Number 2.4516042e7)]))]

Previoulsy when I had this error, I deleted the ledger directory under db and restarted. It went away for some time and then came back again today.
What causes this issue and how to prevent this from happening again?

Im not sure but according to the IOHK documentation is seems to be related to chain forks:

TraceNoLedgerView

Leadership check failed: we were unable to get the ledger view for the current slot number
This will only happen if there are many missing blocks between the tip of our chain and the current slot.

Maybe it can lead you somewhere

Hello,
I am seeing the same errors on my BP node. That’s only what I am seeing, repeating entries for cardano.node.ForgeTime:info followed by cardano.node.LeadershipCheck:Info and then error cardano.node.Forge:Error.

Were you able to resolve this issue?

Hey,

Reading what @Freja wrote could it be that your node has not fully synced with the network?

What do you get if you run cardano-cli query tip --mainnet

Bump. Was this issue every figured out? Having the same problem:

I have a similar issue and wonder if anyone has solved it.
my current version is

$  cardano-cli.sh --version
cardano-cli 1.34.1 - linux-x86_64 - ghc-8.10
git rev 73f9a746362695dc2cb63ba757fbcabb81733d23

but I was curious this error …

@Plot_Cardano

cardano-cli 1.34.1

You should upgrade to 1.35.3 as 1.34.1 is deprecated since the last hard fork.

[Guide] Upgrading to 1.35.3 for CoinCashew Users

I struggled so much while upgrading to the latest version since the information were scatted, so I am going to share the steps that I did and make your life easier: Note: You do all of the below on both of your BP and relays Do the routine updates: sudo apt-get update -y sudo apt-get upgrade -y Update gLiveView automatically: cd $NODE_HOME ./gLiveView.sh # Click yes if it asked you to update Make sure that you have ghc 8.10.7 and cabal 3.6.2.0 (Skip if you already have them): ghcup upg…

Thank you Tiberiu,

But last time I check, probably around mid-Oct, 2022, 1.35.3-configs is on preview, pre-production.
didn’t check then that they fully release it.

• provides configuration file updates for the new Cardano test environments…

What wording in that makes you think that it is not fully released?

In fact, since the Vasil hard fork on September 22nd, you have to run 1.35.3 on mainnet. 1.34.1 will not work anymore at all. And there were a lot of announcements on that.

Preview and preprod are not stages a node software has to go through, but testnets running in parallel to the mainnet. They also require to have 1.35.3 running. They even needed it a little earlier, since they went through the hard fork earlier to test it.

@HeptaSean
This is what it said on the input-output-hk repo around Oct 19, 2022.
"… the release 1.35.3-configs is on preview, pre-production.

Thanks! for the response anyways.

"… the release 1.35.3-configs is on preview, pre-production.

This was about the 1.35.3-configs release with -configs at the end. Never understood why that is there. Looked like it had something to do with enabling the Docker images to run the testnets.

The 1.35.3 release did not contain such perhaps confusing language and has been there since 11th August.

[Plot_Cardano]

Got it now, thank you!
