Hi @pmp,was the **“incorrect nonce”** error a result of a call on your secret contract or is it happening during `discovery start`?

Can you share the link to your repo here?

It happens when I call on the contract during `discovery test`.

I’ve been able to reproduce both of the errors you’re seeing @pmp. The discovery log messages are showing a decryption error when the `new_game()` function is called with arguments. If I call it with no arguments, it works.

```auto

core_1 | building state for 8 contracts

```

I’m still trying to figure out why the args are causing a decryption error, which seems to be happening in the `enclave` code where the task is getting executed.

I’ll let you know what else I come up with!

@pmp I was able to narrow it down to the statement where you’re initializing the `new_sig` array in your `verify()` function. Looks like a typo where you’ve initialized the elements to “0u8” instead of “0”.

It’s not getting called in your tests, but I guess it’s enough to cause an issue when the enclave is trying to execute your `new_game()` function.

Can you verify that changing your `verify()` function, `new_sig` array declaration and initialization from:

```auto
let mut new_sig: [u8; 65] = [0u8; 65];

```

to:

```auto
let mut new_sig: [u8; 65] = [0; 65];

```

resolves the error(s) you were seeing?

Good catch @laura, thank you!

I’m curious, why wouldn’t that mistake have been picked up by the compiler?

Hey @laura, I have another question that I hope you can answer. With the verify() function that was causing errors, I got the code from one of Enigma’s repos: [https://github.com/enigmampc/enigma-core/blob/develop/examples/eng\_wasm\_contracts/erc20/src/lib.rs](https://github.com/enigmampc/enigma-core/blob/develop/examples/eng_wasm_contracts/erc20/src/lib.rs) (Just a note, the error also exists in that code). As you can see it takes a `Vec<u8>` as one of the parameters. How do you pass a `Vec<u8>` type to a secret contract? My instinct was to pass my signature as a hash and call it a `bytes` for the Solidity type e.g.:  
Secret contract:

```auto
#[pub_interface]
pub trait ContractInterface{
    fn new_game(player_1: H160, move_1: String, sig: Vec<u8>);
}

```

And for the Javascript:

```auto
let taskFn = 'new_game(address,string,bytes)';
let taskArgs = [
      [address, 'address'],
      [message, 'string'],
      [signature, 'bytes']
    ];
enigma.computeTask(taskFn, taskArgs, ...);

```

Is this correct?

yeah, I was curious about that too. I tried a simple Rust program and sure enough `rustc` didn’t complain.

@pmp,

Yes, you have it right for passing a `Vec<u8>` type to the secret contract by using the arg type:

```auto
[signature, 'bytes']

```

Here’s a link to the types documentation which includes the mapping of secret contract to Solidity types: [https://enigma.co/discovery-documentation/types/](https://enigma.co/discovery-documentation/types/)

Thank you for pointing out that code in the `erc20` example! I’ll make a note of that.
