I am getting the error: Error: VM Exception while processing transaction: reverted with reason string '11' after the console.log portion that shows my USDC Borrow Available. I have also attached the script which starts running after that console log.

Do you get this error when you clone the repo? Can you try cloning the repo and installing packages and running everything?

Hi Patrick, it works when i used the DAI contracts.. i suspect its got something to do with the USDC decimal places but havent got to troubleshooting yet!

Can't totally understand that.. An elaborated solution will really help me a lot.

This error occur when There is not enough collateral to cover a new borrow.... so check how much you are borrowing..
