Manually setting Gas while submitting a transaction with Hardhat

Support Contracts

1

Its been 3 days since i am regretting that I have built my project on Hardhat. I am using erc1967 proxy with proxyadmin to run my logic contract, Everything is running fine on the local Ganache chain but I am getting an error while I am deploying on the Rinkeby.

Error: cannot estimate gas; transaction may fail or may require manual gas limit

Here is my deployment script.

const hre = require("hardhat");

async function main() {
    // We get the contract to deploy
    // const Greeter = await ethers.getContractFactory("Greeter");
    [account_one,  account_two, account_three] = await hre.ethers.getSigners();

    const initializeData = Buffer.from('');

    const TransparentUpgradeableProxy =  await hre.ethers.getContractFactory('TransparentUpgradeableProxy');
    const ProxyAdmin =  await hre.ethers.getContractFactory('ProxyAdmin');


    const Reputation = await hre.ethers.getContractFactory("Reputation");
    const Posts = await hre.ethers.getContractFactory("Posts");
    
    
    const proxyAdmin = await ProxyAdmin.deploy()
    console.log("proxyadmin deployed to:", proxyAdmin.address);

    const reputation = await Reputation.deploy();
    console.log("Reputation deployed to:", reputation.address);
  


    const reputationProxy = await TransparentUpgradeableProxy.deploy(reputation.address, proxyAdmin.address, initializeData)
    console.log("Reputation Proxy deployed at: posts contract", reputationProxy.address);


    const posts = await Posts.deploy(); 
    await posts.initialize(reputationProxy.address, 5, 130000000, 10)


    // const postsProxyAdmin = await ProxyAdmin.deploy()
    // console.log("proxyadmin deployed to:", postsProxyAdmin.address);


    console.log("Posts deployed to:", posts.address);
    const postsProxy = await TransparentUpgradeableProxy.deploy(posts.address, proxyAdmin.address, initializeData)
    console.log("Posts Proxy deployed at: posts contract", postsProxy.address);




    const reputationProxyContract = await  Reputation.attach(reputationProxy.address);   
    await reputationProxyContract.initialize(postsProxy.address);
    const executor = await reputationProxyContract.getExecutor()
    // await reputation.transferOwnership(postsProxy.address);
    // console.log("Ownership transffered: posts contract");
    console.log("Executor is ", executor)
    // reputationOwner = await reputationProxy.owner.call();
    // console.log("New owner of reputation contract is", reputationOwner);
  }
  
  main()
    .then(() => process.exit(0))
    .catch(error => {
      console.error(error);
      process.exit(1);
    });

The blogs i have read suggested that i should manually set the gas while sending the transaction. I have researching on how to do it but Hardhat being an obsolete project doesn’t have any documentation on it . Please help me here.
