Does anyone know how to print a uint256 in protostar tests?

```
let (local balance) = IERC20.balanceOf(asset, owner);
%{
    balance = reflect.balance.get()
    print("current owner balance: ", balance)
%}
```

this errors out: [https://github.com/software-mansion/protostar/issues/1129](https://github.com/software-mansion/protostar/issues/1129)

Python issues with Pathfinder

1. Can anyone explain how to get Goerli ETH tokens?

2. Also want to know how to bridge tokens from the Goerli ETH testnet and move them to Goerli2 (StarkNet)?

> thank's for your answers, summing up how to transfer funds and how to use Faucet on Ethereum:


1. For receiving ETH on Goerli Test Net, I used [Goerli PoW Faucet](https://goerli-faucet.pk910.de/).
As an alternative, [https://goerlifaucet.com/](https://goerlifaucet.com/) can be used, but it is required to authorize.

2. I installed ArgentX using the links below and transferred funds using the [HashStack service for StarkNet](https://goerli2-bridge.hashstack.finance)

StarkNet Faucet: How can I get a Goerli-2 eth faucet tokens (StarkNet)?

In the following function I am presented with the following error, even though my code does not make it to this function. What am I doing wrong?


`func fill_in_row{output_ptr: felt*}(row_idx : felt, row_size : felt, curr_row : felt*) {` 


 `if (row_idx == row_size-2) {`


 `return ();`


 `}`


 `let val : felt = curr_row[row_idx-1] + curr_row[row_idx];`


 `serialize_word(val);`


 `curr_row[row_idx+1] = val;`


 `return fill_in_row(row_idx+1, row_size, curr_row);`


`}`


Error: code:80:5: While expanding the reference 'curr_row' in:


 curr_row[row_idx+1] = val;


 ^******^


code:72:73: Expected a register. Found: [fp + (-4)].

Do you have any idea on how much is starknetJS request limit?

Hello, Do I understand this correctly: Pathfinder JSON-RPC V0.1.0 does not support InvokeTXNV1 yet, right? At least, I do not `nonce` in `add_invoke_transaction`.

Do you plan to add it in JSON-RPC V0.1.0 like devnet (not being compliant to the spec) or will you introduce it with JSON-RPC V0.2.0?
