Setting gas for contract creation on script #14026

Describe the feature you would like

I need to setup the gas limit for deploying a contract (it's on Besu, so the estimate gas works weird).
I have try to do it like this

authList = new AuthList{gas: 1000000000000000000}(authListOwner);

But it says that gas is not a valid key for new.
There's a way to set the gas limit when deploying a contract?

This is a Solidity language limitation, only the salt and value parameters are valid for new.

Could you expand on the issues / limitations you are facing with Besu? Perhaps we can improve support for it in Foundry.

Perhaps try the --gas-estimate-multiplier <N> where N is a multiplier in percentage terms, 200 meaning 2 times gas

I have created a script to deploy a very large set of contracts for a Hyperledger Besu Proof of Concept.
The script works perfectly on Anvil
When I try to run on Besu, I get this error:

The line to execute the script: forge script .... --gas-price 0 --priority-gas-price 0 --gas-limit 90000000 --broadcast --skip-simulation
PD: the Besu networks runs on gas price 0 and no gas limit (it's an absurd amount)

Error: Failed to send transaction after 4 attemps- Err (Failed to estimate gas)
Context: Failed to build transaction: AnyTxType(2) transaction can't be build due to missing keys ['gas_limit']

@title MasterDeployer
@notice Foundry deployment script that reads deploy-config.json and deploys

    the complete BCentral POC platform.

Usage:
forge script script/MasterDeployer.sol \

--rpc-url <rpc_url> --private-key <bc_admin_key> --broadcast

IMPORTANT: The --private-key MUST correspond to bancoCentral.admin.wallet
in deploy-config.json. All privileged calls (addAdmin on BancoCentral and
participant banks) are made as the broadcaster in a single broadcast session.
Expected deploy-config.json structure (ALL keys required; arrays may be []):
{
```
"network": {
```
```
  "chainId": "0x7a69",
```

  "chainName": "Banco Central - Anvil",

```
  "rpcUrl": "http://127.0.0.1:8545",
```
```
  "nativeCurrencyName": "GO Token",
```
```
  "nativeCurrencySymbol": "GO",
```
```
  "nativeCurrencyDecimals": "18"
```
```
},
```
```
"b2cAuth": {
```
```
  "tenant": "labbcch",
```

  "clientId": "5e7a78ce-ff62-4be4-87f0-72619b0ff43b",

  "policy": "B2C_1_Blockchain_webed_login",

  "redirectUri": "http://localhost:3000"

```
},
```
```
"bancoCentral": {
```

  "admin": { "wallet": "0x...", "username": "...", "name": "..." },

```
  "additionalAdmins": []
```
```
},
```
```
"dcv": {
```

  "admin": { "wallet": "0x...", "username": "...", "name": "..." }

```
},
```
```
"mdbc": { "initialSupply": "..." },
```
```
"banks": [
```
```
  {
```
```
    "name": "...", "code": "...",
```

    "admin": { "wallet": "0x...", "username": "...", "name": "..." },

```
    "additionalAdmins": []
```
```
  }
```
```
]
```
}
Deployment steps (execution order):
1. Validate deploy-config.json
1. Deploy AuthList
1. Deploy IRFOwnersFactory
1. Deploy PDBCFactory, BCUFactory, BEFactory
1. Deploy IRFFactory (with the 4 sub-factories)
1. Deploy BankFactory
1. Deploy DCV
1. Deploy DvP
1. Deploy BancoCentral
1. Deploy MasterConfig + setMasterConfig on IRFFactory
1. Deploy CLUFOracle
1. Register BancoCentral in AuthList (INSTITUTION_ROLE)
1. Register address(0) in AuthList (VAULT_ROLE)
1. Register BancoCentral vault in AuthList (VAULT_ROLE)
1. Create participant banks + register in AuthList
1. Transfer AuthList ownership -> BancoCentral
1. Transfer BankFactory ownership -> BancoCentral
1. Deploy MDBC
1. Add additional admins to BancoCentral
1. Generate .env file
Note on bank admin setup: participant banks are created before the ownership
transfers (steps 16-17) so the broadcaster can still register banks in AuthList
and call addAdmin directly. The broadcaster (bcAdmin.wallet) is set as the
initial bank admin to retain DEFAULT_ADMIN_ROLE; the bank's own configured
admin is then added immediately after, followed by any additional admins.
