Pathfinder initially sends many queries to the Ethereum endpoint, but once it is in sync this lessens and can become so low that Alchemies dashboard shows it as zero requests. This is normal behaviour and is not a cause for alarm.

As a sanity check, the Alchemy dashboard underneath it should show some active recent requests (at least one every 15 minutes or so).

Hey there! 

I am using the Oz Nile framework for smart contract development on Starknet. More specifically, I am testing the proxy upgrade feature, but my tests fail with the error message TypeError: int() can't convert non-string with explicit base. This happens when nile.signer tries to sign a transaction. Here's the snippet in the stack trace below. 

```
def sign_transaction(self, sender, calls, nonce, max_fee):
        """Sign a transaction for an Account."""
        (call_array, calldata) = from_call_to_call_array(calls)
        message_hash = get_transaction_hash(
>           int(sender, 16), call_array, calldata, nonce, int(max_fee)
        )
```

Some relevant info:
cairo-lang==0.10.0
cairo-nile==0.8.2
openzeppelin-cairo-contracts==0.4.0b
pytest==7.1.2
python=3.9
