second parameter in solidity contact methode crashes sepolia node

solidity contract on my ethereum sepolia node deployment

## Description
I would like to install a **simple** solidity contract on my ethereum sepolia node.
It works, but if each method has only one parameter.
With two parameters e.g. **uint bla** in the method I get 500 errors from the server.

## Environment

- "ethers": "6.13.5",
- "hardhat": "2.22.17",
- solidity 0.8.28;

## Steps to Reproduce

```solidity
pragma solidity 0.8.28;

contract SimpleStorage {
uint storedData;

function set(uint x, uint bla) public {
storedData = x;
}

function get() public view returns (uint) {
return storedData;
}
}

Reproduce the SimpleStorage deployment on an Ethereum Sepolia node using Solidity 0.8.28, ethers 6.13.5, and Hardhat 2.22.17. Compare a one-parameter method with set(uint x, uint bla), capture the 500 response, and determine whether the failure is in the Solidity contract, transaction handling, or node/server integration.
