Couldn't read Hardhat config file

[alexanderattar]

Hello,

I have been trying to get Tenderly setup locally in a project to be able to push up the contracts and verify for debugging purposes, but have not been successful due to receiving the error Couldn't read Hardhat config file with any variation of config even when taking out more complex aspects of our project's config and trying the simplest config file I can think of. Running the command tenderly contracts push --debug I get the full error output below:

✗ tenderly contracts push --debug

Couldn't read Hardhat config file

I have tried even with making the config file as simple as possible with the code below:

require('@tenderly/hardhat-tenderly');

export default {
  solidity: '0.8.13',
  defaultNetwork: 'sepolia',
  networks: {
    sepolia: {
      url: `https://eth-sepolia.g.alchemy.com/v2/MY_API_KEY`,
    },
  },
};

Am I missing something simple or is this a weird bug? Here are my dependencies for context unless there is a known issue:
