Gas estimation failed Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending? Error happened while trying to execute a function inside a smart contract

I'm following the tutorial exactly as it is but in the last part when I try to call the requestFlashLoan function with the same parameters I always get this error: "Gas estimation failed
Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Error happened while trying to execute a function inside a smart contract."

Any solution?
