fallback return value "bytes memory" isn't asigned,

[FinagleLord]

fallback(bytes calldata _input) external returns (bytes memory) { (address sender, uint256 amount0, uint256 amount1, bytes memory data) = abi.decode(_input[4:], (address, uint256, uint256, bytes)); uniswapV2Call(sender, amount0, amount1, data); }

would this be a solution?

fallback(bytes calldata _input) external returns (bytes memory) { (address sender, uint256 amount0, uint256 amount1, bytes memory data) = abi.decode(_input[4:], (address, uint256, uint256, bytes)); uniswapV2Call(sender, amount0, amount1, data); return data; }

in the solution i just added "return data;" at the end

I have tried, but when making the call to "flashArbitrage", it gives me a "fail" when executing the contract. If we edit the invocation line:

"IUniswapV2Pair (info.lowerPool) .swap (amount0Out, amount1Out, address (this), data);"
by:
"IUniswapV2Pair (pair0) .swap (amount0Out, amount1Out, address (this), data);"

I am able to move forward a bit but it gives me a pancake error "Fail with error 'Pancake: LOCKED'"

Any solution?
