Two arbitrage opportunities have been logged but failed with error Fail with error 'SafeERC20: low-level call failed'

The transactions are:

I suspect there might be a bug with the contract, or maybe with these specific pairs?

@yuichiroaoki do you happen to know why this would fail?

That error message is ambiguous, but it happens when you try to borrow more tokens than the dodo pool has.

How can I customize it to borrow minimum from the pool? if I run this command npx hardhat run scripts/flashloan.ts it will always print the same address from the terminal, also the txn hash is not found on polygon scan but when I run npx hardhat run scripts/flashloan.ts --network polygon I will get this error massage Fail with error 'SafeERC20: low-level call failed

That error message is ambiguous, but it happens when you try to borrow more tokens than the dodo pool has. please help on how to customize it Screenshot (30)
