Hi

Are the config files for the block producing node not available on the links as in the course hand notes?

I’m getting an ERROR 404: Not Found.

These are the urls as in the course…

wget [https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/shelley\_testnet-config.json](https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/shelley_testnet-config.json)

wget [https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/shelley\_testnet-shelley-genesis.json](https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/shelley_testnet-shelley-genesis.json)

wget [https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/shelley\_testnet-topology.json](https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/shelley_testnet-topology.json)

Anyone else faced this issue and know how to solve it?

Thank you!

Correct link would be:

Thank you Lauris!

The link to the topology file seems to be new/ invalid?  
[https://explorer.cardano-testnet.iohkdev.io/relays/topology.json](https://explorer.cardano-testnet.iohkdev.io/relays/topology.json)

I’m seeing this error:  
cardano-node: FatalError {fatalErrorMessage = “Cardano.Node.Run.createTracers.readTopologyFile: Is your topology file formatted correctly? The port and valency fields should be numerical. Error in $: empty”}

I suspect it’s because the topology format doesn’t include valency.

The Topology file from your link above has only one node so not sure if that’s enough for a relay node.

Any clarification would be highly appreciated!

Thanks!
