Smart Contract deployment error

Question

I am trying to deploy a smart contract on Rinkeby testnet and I am getting the following error

truffle-config.js settings

  networks: {
    development: {
     host: "127.0.0.1",     // Localhost (default: none)
     port: 8545,            // Standard Ethereum port (default: none)
     network_id: "*",       // Any network (default: none)
    },
rinkeby: {
  provider: () => new HDWalletProvider(mnemonic, `https://rinkeby.infura.io/v3/${projectId}`),
  network_id: 4,       // Rinkeby's id
  gas: 8500000,        
  gasPrice: 1000000000,  // 1 gwei (in wei) (default: 100 gwei)
  confirmations: 2,    // # of confs to wait between deployments. (default: 0)
  timeoutBlocks: 200,  // # of blocks before a deployment times out  (minimum/default: 50)
  skipDryRun: true     // Skip dry run before migrations? (default: false for public nets )
},}

I was following the following link for the deployment

Answer 1

It's normal that sometimes a transaction with a higher gas price than yours have been submitted around the time as your transaction. You can increase the gas price, and resubmit the transaction later. Also make sure you check the transaction pool of your node to ensure a miner existed in your network.
