heya, trying here maybe i'll get some help :S (it's related to balancer but i'm not getting any response from them).

I'm trying to make a swap via balancer and it's failing and I have no clue into why

This is what i'm trying to do:
(swaps ,myBalamountOut) = BalancerProxy.viewSplitExactIn(tokenIn, tokenOut, amount, 10);

//TIERC20TokenIn.approve(address(BalancerProxy), amount);
//balancerPayable.transfer(amount);
_wrapEth(amount);
WETH.approve(address(BalancerProxy), amount);

//totalAmountOut = BalancerProxy.batchSwapExactIn{value: amount}(swaps, ERC20TokenIn, ERC20TokenOut, amount, myBalamountOut);
totalAmountOut = BalancerProxy.smartSwapExactIn(TIERC20TokenIn, TIERC20TokenOut, amount, myBalamountOut, 10);

I'm trying many things but none worked :-(
the call just fail with " Warning! Error encountered during contract execution [Bad instruction] "
