Video 14 Configuring hardhat Export Fix

[JaredHightower]

##TypeError: Cannot read properties of null (reading 'sendTransaction')

Solution

I was able to figure out what was causing this issue. In video 14 Configuring Hardhat within the Mumbai object change account to accounts. The source of the solution can be found here

module.exports = {
  solidity: "0.8.2",
  networks: {
    mumbai: {
      url: process.env.MUMBAI_RPC,
      account: [process.env.PRIVATE_KEY] // <--- Fix this line: the key should accounts NOT account
    }
  }
};
