Handshake error

while starting the the nsd i am facing the below error:

I[2019-07-10|14:17:42.569] Starting ABCI with Tendermint module=main
ERROR: error during handshake: error on replay: validator set is nil in genesis and still empty after InitChain

hello! it looks to me like you need to finish following the instructions in the build-run portion of the tutorial. https://cosmos.network/docs/tutorial/build-run.html

You need to create at least on key and use it to sign a genesistx which will add your key as a validator to genesis.json. Follow the CLI commands and see if that works (add-genesis-account… etc)
