I am quite new to coding with limited experience, after following the Patrick Collins tutorial on flash loans from AAVE, everything works fine and have the environment installed.

I receive this error upon deploying:

  • **(1)** Is this [Youtube video](https://www.youtube.com/watch?v=Aw7yvGFtOvI&ab_channel=PatrickCollins) what you mean? If yes try to include such information. Nobody knows what tutorial you followed to get that problem. **(2)** Also I'm guessing this is on Windows (not Linux or such)?... – VC.One Jan 10 '22 at 10:42
  • Hi, thanks for the response, yes that is correct this is the tutorial I followed (https://www.youtube.com/watch?v=Aw7yvGFtOvI). I am using Windows 11 – jonnykashhh Jan 11 '22 at 10:19
  • to add to the above, the error occurs when I run the get WETH command: brownie run scripts/get_weth.py --network kovan – jonnykashhh Jan 11 '22 at 10:37
  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Jan 19 '22 at 01:13
