Lesson16: TypeError: invalid value for Contract target at line 7:22

[0xCK03]

While running :

yarn hardhat run scripts/upgrade-box.js --network localhost

I'm facing the following error while running "upgrade-box.js".

TypeError: invalid value for Contract target (argument="target", value=null, code=INVALID_ARGUMENT, version=6.12.0)

}

Here is "upgrade-box.js"

async function main() {
  const BoxProxyAdmin = await ethers.getContract("BoxProxyAdmin");
  const transparentProxy = await ethers.getContract("Box_Proxy");

  const proxyBoxV1 = await ethers.getContractAt(
    "Box",
    transparentProxy.address
  );
  const versionV1 = await proxyBoxV1.version();
  console.log(versionV1);
  const boxV2 = await ethers.getContract("BoxV2");
  const upgradeTx = await BoxProxyAdmin.upgrade(
    transparentProxy.address,
    boxV2.address
  );
  await upgradeTx.wait(1);

  const proxyBoxV2 = await ethers.getContractAt(
    "BoxV2",
    transparentProxy.address
  );
  const versionV2 = await proxyBoxV2.version();
  console.log(versionV2);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });
