ethpm/Lobby

I'd appreciate a bit of help with publishing to the Ropsten sub-domain of infura.io via Truffle, currently I'm receiving a insufficient funds for gas * price + value error.

Command Input

cd ~/git/hub/solidity-utilities/library-mapping-address

truffle publish

Error Output

Finding publishable artifacts...
Uploading sources and publishing to registry...
insufficient funds for gas * price + value
Truffle v5.4.10 (core: 5.4.10)
Node v16.10.0

Questions

• According to documentation I could find, EthPM packages are published to a test network, so how does one fund such transactions?

• I'm currently using a private-key for HDWalletProvider signing, do I also need to provide the "Project Secret" generated by Infura?

Configuration files

const ethpm_file = `${path.join(os.homedir(), ".ethpm.json")}`;

  try {
    HDWalletProvider = require("@truffle/hdwallet-provider");
    ethpm = require(`${path.join(os.homedir(), ".ethpm.json")}`);
  } catch (error) {
    console.warn('Warning: ignored ->', error.message);
  }
}
