Cannot deploy on BSC Testnet

aress31 · May 1, 2021, 12:41am

I am unable to deploy the following contract on the BSC TestNet using Truffle v5.3.2 (core: 5.3.2):

aress31/ERC20-deflationary/blob/main/contracts/ERC20Deflationary.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.4;

import "@openzeppelin/contracts/access/Ownable.sol";

import "@uniswap/v2-periphery/contracts/interfaces/IUniswapV2Router01.sol";
import "@uniswap/v2-periphery/contracts/interfaces/IUniswapV2Router02.sol";

contract ERC20Deflationary is ERC20Burnable, Ownable {
    // liquidity pool provider router
    IUniswapV2Router02 public _uniswapV2Router;

    address public _uniswapV2Pair;
    address private constant burnAccount =
        0x000000000000000000000000000000000000dEaD;
    address _router;

I spent the past week trying to troubleshoot it, changing gas fees and compiler options and nothing works keep getting this annoying error message:
