probable due to missing module param:

./liked-3.0.0-alpha4 --node tcp://52.187.27.20:26657 --chain-id likecoin-skynet-1 query likenft params
Error: rpc error: code = Unknown desc = panic message redacted to hide potentially sensitive system info: panic

[elise-ng]

to add missing param:

  "title": "Set LikeNFT module params",
  "description": "Set LikeNFT MintPriceDenom param to nanolike",
  "changes": [
    {
      "subspace": "likenft",
      "key": "MintPriceDenom",
      "value": "nanolike"
    }
  ],
  "deposit": "10000000nanolike"
}

./liked tx gov submit-proposal param-change ./param-change.json --from azure --keyring-backend file --chain-id likecoin-skynet-1
./liked tx gov vote 1 yes --from azure --keyring-backend file --chain-id likecoin-skynet-1

[elise-ng]

fixed after param change proposal, however, found that the end blocker was not executing as expecting, seems we missed registering it in module.go; debugging now

[elise-ng]

end block issue fixed with alpha5;

results can be found via: http://52.187.27.20:26657/block_results?height=31823
