Metamask Aave loan repayment - Error getting txParams

thanks for detailed response. how do you know it is an error with paraswap?
i had the error when trying to repay USDT loan with USDT.
the error popped up before i was able to approve “allow me to approve USDT to continue”

I just have to say thank you for this! I’m glad I stumbled onto the forum. I had a huge issue w this, and revoking the approval on Etherscan worked!
