I assume that this means the transaction works but the profit margin isn't high enough to pay back the loan. But unlike the Uniswap errors that have an output like "INSUFFICIENT LIQUIDITY" or "INSUFFICIENT OUTPUT AMOUNT" which can easily be traced back to in the UniswapV2Pair.sol contract this one has no such output and therefore I cannot trace it back in the contracts.
The traceback does point to the swap function call in my arbitrage contract but it gives no other info. However, there is no such error in the UniswapV2Pair contract.
Anyone know how to learn more about this error?
