Truffle Deployment Error: has no network configuration for its current network id (97)

Question

I'm having an issue deploying a contract with Truffle. The contract constructor takes 7 parameters which are all within the 2_deploy_xxx.js file. However, every time I do, I get an error when I get to deploying the actual contract. The contract takes an oracle (AggregatorV3Interface from ChainLink). I'm stumped and wondered if anyone would be able to help me as I've stared at this for too long.

truffle-config.js

const HDWalletProvider = require('truffle-hdwallet-provider');
require('dotenv').config();

const BSC_DEPLOYER_KEY = process.env.BSC_DEPLOYER_KEY;
const BSC_TESTNET_DEPLOYER_KEY = process.env.BSC_TESTNET_DEPLOYER_KEY;

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 8545,
      network_id: "*",
    },
    testnet: {
      provider: () => new HDWalletProvider(BSC_TESTNET_DEPLOYER_KEY, `https://data-seed-prebsc-1-s1.binance.org:8545`, 0, 10),
      network_id: 97,
      confirmations: 10,
      timeoutBlocks: 200,
      skipDryRun: true,
      from: 'address',
    },
    bsc: {
      provider: () => new HDWalletProvider(BSC_DEPLOYER_KEY, `https://bsc-dataseed1.binance.org`),
      network_id: 56,
      confirmations: 10,
      timeoutBlocks: 200,
      skipDryRun: true,
    },
  },
  plugins: [
    'truffle-plugin-verify'
  ],
  api_keys: {
    etherscan: process.env.BSCSCAN_API_KEY
  },
  mocha: {
    // timeout: 100000
  },

  compilers: {
    solc: {
      version: "0.6.12",

        optimizer: {
          enabled: true,

        },
      }
    },
  }
}

2_deploy_prediction.js

const BnbPricePrediction = artifacts.require("BnbPricePrediction");
const AggregatorV3Interface = artifacts.require("AggregatorV3Interface");

const ADMIN_ADDRESS = '';
const OPERATOR_ADDRESS = '';

    let bufferBlocks = BUFFER_BLOCKS;
    let minBetAmount = MIN_BET_AMOUNT;
    let oracleUpdateAllowance = ORACLE_UPDATE_ALLOWANCE;

    deployer.deploy(AggregatorV3Interface);

    let oracle = AggregatorV3Interface.address

    deployer.deploy(
        BnbPricePrediction,
        oracle,

Answer 1

The solution to my issue was removing AggV3Int as a required artifact, assigning the address of an already deployed oracle, and changing the deployer function to be async awaiting deployer.deploy.

Answer 2

What are the extra 2 parameters 0 and 10 with the testnet link? I think if you change provider: () => new HDWalletProvider(BSC_TESTNET_DEPLOYER_KEY, https://data-seed-prebsc-1-s1.binance.org:8545, 0, 10),

to

provider: () => new HDWalletProvider(BSC_TESTNET_DEPLOYER_KEY, https://data-seed-prebsc-1-s1.binance.org:8545),

It should work.
