I have deployed smart contract which buys token using 0x Settler. I am seeing an error 
```shortMessage: 'contract runner does not support calling'```

Here is the process
 * call 0x API and get quote for swapping ETH for TokenA
 * response has `transaction.data` which is passed to below 'swapCallData' . Pass Settler address and TokenA address

you will see error 
```shortMessage: 'contract runner does not support calling'```

@matchaxyz do you have updated docs ?

New issue receiving ```Error: Transaction reverted: function selector was not recognized and there's no fallback function``` It seems the fallback function is not called, because I am not using Permit2. I got the function and might have to reverse engineer the params.
