Now, We will take a scenario from DSA which will throw an error of `gas required exceeds allowance` which is quite common.
We will try to cast the oasis’ sell spell and maker’s borrow spell with amount 0.2 DAI and slippage 1%.

Now, If we will cast the above spells, then it will thrown an error of `gas required exceeds allowance`. But it doesn’t give any clue why it is throwing this error.
So, now we can use the DSA’s estimateCastGas() function which provide us the amount of gasLimit we need to provide to the spells and in its Catch section we will print the error which will give us the data variable in case any error occurs.

Now, after executing the dsa.estimateCastGas() function, it will return us error along with the data variable which we will use at tenderly.

Now, When we simulate the transaction it will tell us with the whole call stack and if the transaction will go through or not.

In our case, it is showing that the transaction has failed along with an error `execution reverted`.
But this time the error is quite understandable as it is providing us the condition which caused the error which in our case is `require(managerContract.count(address(this)) > 0, "no-vault-opened");`. Now, we can understand the error and work on solving it.

If you want to know about the contracts that were involved in the transaction you can navigate to the `Contracts` section and take a look.

There is also a feature of `Gas Profiler` which provides you with a gas usage breakdown by the function call.
