Help with StarkNet Contract Interaction: run_system Function Returning 'Input too short for argument

[otatataata]

Hi,

I'm working on integrating with a blockchain-based game called Influence that operates on StarkNet, a Layer 2 Ethereum scaling solution. I'm trying to call a smart contract function, run_system, which executes certain game actions. However, I'm running into an error that I can't seem to resolve.

The Problem:

When I attempt to execute the function with the following calldata, I receive the error: "Execution failed. Failure reason: 'Input too short for arguments'."

Here is the relevant part of my code:

calldata = [
    4164017864394795057807229457414135500561370437549190888616,  # "ExtractResourceFinish"
    6,      
    5,      
    5,      
    7809, 
    1,      
    1,     
    4329    
]

try:
    prepared_invocation = contract.functions["run_system"].prepare_invoke_v1(name, calldata)
    # ... executing the transaction
except Exception as e:
    print(f"Error: {e}")

Error: Execution failed. Failure reason: 'Input too short for arguments.

Here is the relevant part of the ABI for the run_system function:

[
    {
        "name": "run_system",
        "type": "function",
        "inputs": [
            {
                "name": "name",
                "type": "felt252"
            },
            {
                "name": "calldata",
                "type": "array"
            }
        ],
        "outputs": [
            {
                "type": "array"
            }
        ],
        "state_mutability": "external"
    }
]

Here is the definition of ExtractRessourceFinish:

    "type": "function",
    "name": "ExtractResourceFinish",
    "inputs": [
      {
        "name": "extractor",
        "type": "influence::common::types::entity::Entity"
      },
      {
        "name": "extractor_slot",
        "type": "core::integer::u64"
      },
      {
        "name": "caller_crew",
        "type": "influence::common::types::entity::Entity"
      }
    ],
    "outputs": [],
    "state_mutability": "external"
  },

When i copy the transaction in argent X here are the arguments: [
"0x457874726163745265736f7572636546696e697368",
"0x5",
"0x5",
"0x123c",
"0x1",
"0x1",
"0xb16"
]

Hi @otatataata, please check if you properly serialize the input. In the starknet.py we have a few classes that can help you

If your input is simple, you can do it by hand for example reading this docs - link
