Hi, I am going through the Stake Pool course, but I am stuck at this stage [Start your core node - Stake pool course (gitbook.io)](https://cardano-foundation.gitbook.io/stake-pool-course/stake-pool-guide/stake-pool/corenode-start)

My code for that section looks like this

> ```
> cardano-node run \
> --topology testnet-topology.json \
> --database-path /db \
> --socket-path /db/node.socket \
> --host-addr 0.0.0.0 \
> --port 3001 \
> --config testnet-config.json \
> --shelley-kes-key kes.skey \
> --shelley-vrf-key vrf.skey \
> --shelley-operational-certificate node.cert
> 
> ```

but I get this error

> `There was an error parsing the genesis file: ./testnet-shelley-genesis.json Error: GenesisDataParseError "(line 2, column 24):\nunexpected \".\"\nexpecting white space, \",\" or \"}\""`

I got the testnet-shelley-genesis.json file from an earlier part of the course [Configure topology files for block-producing and relay nodes. - Stake pool course (gitbook.io)](https://cardano-foundation.gitbook.io/stake-pool-course/stake-pool-guide/stake-pool/core_relay)

and it is this

Anyone else had this problem or knows where I went wrong? I am new to Linux and stake-pools so I might have made a very stupid error along the way

Thanks, but it didn’t work. I will do it all over again, but this time following this guide instead [8. Register a Stake Pool with Metadata — cardano-node Documentation 1.0.0 documentation](https://docs.cardano.org/projects/cardano-node/en/latest/stake-pool-operations/register_stakepool.html#create-a-json-file-with-your-pool-s-metadata)

I will see how it goes
