Gas estimation on contract deployment with payable constructor reverts

[natanasow]

Description

If we try to estimate gas for a contract deployment with a payable constructor, the web3 module reverts instead of returning a proper gas value.

Steps to reproduce

We have a simple contract:

pragma solidity ^0.8.24;

contract PayableConstructor {
    constructor() payable {}
}

The bytecode is:

0x6080604052603e80600f5f395ff3fe60806040525f80fdfea2646970667358221220a38ca427a091f1d38af455b9ec034fe31be0290310c3e2888017a1fce83553d464736f6c634300081a0033

---

• if we execute a gas estimation against the mirror node web 3 module via POST to https://testnet.mirrornode.hedera.com/api/v1/contracts/call with that body:

{
    "value":1000000,
    "estimate": true,
    "from":"0x6e5d3858f53fc66727188690946631bde0466b1a",
    "data":"0x6080604052603e80600f5f395ff3fe60806040525f80fdfea2646970667358221220a38ca427a091f1d38af455b9ec034fe31be0290310c3e2888017a1fce83553d464736f6c634300081a0033"
}

it reverts with a:

{
    "_status": {
        "messages": [
            {
                "message": "Bad Request",
                "detail": "to field must not be empty",
                "data": ""
            }
        ]
    }
}

• if we remove the value from the body:

{
    "estimate": true,
    "from":"0x6e5d3858f53fc66727188690946631bde0466b1a",
    "data":"0x6080604052603e80600f5f395ff3fe60806040525f80fdfea2646970667358221220a38ca427a091f1d38af455b9ec034fe31be0290310c3e2888017a1fce83553d464736f6c634300081a0033"
}

then we get a expected result:

{
    "result": "0x000000000000e228"
}

I also tried passing "to" as a null or empty string but it failed again.
