Implementing Uniswap v3 API single swap example on scaffold-eth - ERROR: cannot estimate gas

Using scaffold-eth to implement this single swap example from the uniswap documentation.

Pretty much just copied and pasted the code and was able to deploy it successfully to rinkeby:

//SPDX-License-Identifier: MIT

import "hardhat/console.sol";
import '@uniswap/v3-periphery/contracts/interfaces/ISwapRouter.sol';
import '@uniswap/v3-periphery/contracts/libraries/TransferHelper.sol';

contract YourContract {
  // For the scope of these swap examples,
  // we will detail the design considerations when using
  // `exactInput`, `exactInputSingle`, `exactOutput`, and  `exactOutputSingle`.

  // It should be noted that for the sake of these examples, we purposefully pass in the swap router instead of inherit the swap router for simplicity.
  // More advanced example contracts will detail how to inherit the swap router safely.

  ISwapRouter public immutable swapRouter;

  // This example swaps DAI/WETH9 for single path swaps and DAI/USDC/WETH9 for multi path swaps.

  address public constant DAI = 0x6B175474E89094C44Da98b954EedeAC495271d0F;
  address public constant WETH9 = 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2;
  address public constant USDC = 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48;

  // For this example, we will set the pool fee to 0.3%.
  uint24 public constant poolFee = 3000;

  constructor(ISwapRouter _swapRouter) {
      swapRouter = _swapRouter;
  }

  /// @notice swapExactInputSingle swaps a fixed amount of DAI for a maximum possible amount of WETH9
  /// using the DAI/WETH9 0.3% pool by calling `exactInputSingle` in the swap router.
  /// @dev The calling address must approve this contract to spend at least `amountIn` worth of its DAI for this function to succeed.
  /// @param amountIn The exact amount of DAI that will be swapped for WETH9.
  /// @return amountOut The amount of WETH9 received.
  function swapExactInputSingle(uint256 amountIn) external returns (uint256 amountOut) {
      // msg.sender must approve this contract

      // Transfer the specified amount of DAI to this contract.
      TransferHelper.safeTransferFrom(DAI, msg.sender, address(this), amountIn);

      // Approve the router to spend DAI.
      TransferHelper.safeApprove(DAI, address(swapRouter), amountIn);

      // Naively set amountOutMinimum to 0. In production, use an oracle or other data source to choose a safer value for amountOutMinimum.
      // We also set the sqrtPriceLimitx96 to be 0 to ensure we swap our exact input amount.
      ISwapRouter.ExactInputSingleParams memory params =
          ISwapRouter.ExactInputSingleParams({
              tokenIn: DAI,
              tokenOut: WETH9,
              fee: poolFee,
              recipient: msg.sender,
              deadline: block.timestamp,
              amountIn: amountIn,
              amountOutMinimum: 0,
              sqrtPriceLimitX96: 0
          });

      // The call to `exactInputSingle` executes the swap.
      amountOut = swapRouter.exactInputSingle(params);
  }

  /// @notice swapExactOutputSingle swaps a minimum possible amount of DAI for a fixed amount of WETH.
  /// @dev The calling address must approve this contract to spend its DAI for this function to succeed. As the amount of input DAI is variable,
  /// the calling address will need to approve for a slightly higher amount, anticipating some variance.
  /// @param amountOut The exact amount of WETH9 to receive from the swap.
  /// @param amountInMaximum The amount of DAI we are willing to spend to receive the specified amount of WETH9.
  /// @return amountIn The amount of DAI actually spent in the swap.
  function swapExactOutputSingle(uint256 amountOut, uint256 amountInMaximum) external returns (uint256 amountIn) {
      // Transfer the specified amount of DAI to this contract.
      TransferHelper.safeTransferFrom(DAI, msg.sender, address(this), amountInMaximum);

      // Approve the router to spend the specifed `amountInMaximum` of DAI.
      // In production, you should choose the maximum amount to spend based on oracles or other data sources to achieve a better swap.
      TransferHelper.safeApprove(DAI, address(swapRouter), amountInMaximum);

      ISwapRouter.ExactOutputSingleParams memory params =
          ISwapRouter.ExactOutputSingleParams({
              tokenIn: DAI,
              tokenOut: WETH9,
              fee: poolFee,
              recipient: msg.sender,
              deadline: block.timestamp,
              amountOut: amountOut,
              amountInMaximum: amountInMaximum,
              sqrtPriceLimitX96: 0
          });

      // Executes the swap returning the amountIn needed to spend to receive the desired amountOut.
      amountIn = swapRouter.exactOutputSingle(params);

      // For exact output swaps, the amountInMaximum may not have all been spent.
      // If the actual amount spent (amountIn) is less than the specified maximum amount, we must refund the msg.sender and approve the swapRouter to spend 0.
      if (amountIn < amountInMaximum) {
          TransferHelper.safeApprove(DAI, address(swapRouter), 0);
          TransferHelper.safeTransfer(DAI, msg.sender, amountInMaximum - amountIn);
      }
  }
}

Also learned to edit my deployer to add in the args for the constructor, and made sure to pass the SwapRouter address from here:

await deploy("YourContract", {
    // Learn more about args here: https://www.npmjs.com/package/hardhat-deploy#deploymentsdeploy
    from: deployer,
    args: [ '0xE592427A0AEce92De3Edee1F18E0157C05861564' ],
    log: true,
    waitConfirmations: 5,
  });

This all worked, and I am able to see this in the debug console on my local scaffold-eth, running on rinkeby:

I also made sure to have enough funds in my wallet for gas, etc:

When I try to hit send in the swapExactInputSingle function for any amount of DAI, I get the following error every time:

{
   "reason":"cannot estimate gas; transaction may fail or may require manual gas limit",
   "code":"UNPREDICTABLE_GAS_LIMIT",
   "error":{
      "code":-32000,
      "message":"execution reverted"
   },
   "method":"estimateGas",
   "transaction":{
      "from":"0xF59FBfd44C9e495542D46109F81416bd3fC38Ed7",
      "to":"0xcFc57b48365133105F6877a02126673B7b906a55",
      "data":"0x73bd43ad000000000000000000000000000000000000000000000000000000000000000a",
      "accessList":null
   }
}

I get this error as soon as I hit send, and am never prompted to approve my DAI or anything else. Other simple contracts have worked and I am able to send transactions on Rinkeby properly, so assume this is due to the added complexity of using the Uniswap API, etc.
