Spam fails on ```getReserves()``` call

When trying to call `yarn script.spam --mempool` or `./bin/run spam -l deployment.json` after successful deployment
I receive the following error in both cases:
```

const error: any = new Error(message);

I traced the error to the `daiWethB` contract. Additional suggestions are greatly appreciated
