Nautilus.js fails with invalid address on publish() using custom Pontus-X network despite providing manual configuration

[JATN1506]

Description
I am building a data service using @deltadao/nautilus and ethers.js (v5.8.0) in an AdonisJS environment. I am trying to publish a Data Asset on the Pontus-X Testnet (Chain ID 32457).

Since this network is not part of the default ocean.js ConfigHelper, I am passing a manualConfig object to the Nautilus.create() method.

The Issue
During the execution, the console logs: No config found for given network '32457'.

Immediately after, when calling nautilus.publish(asset), the process crashes with the following error from Ethers: Error: invalid address or ENS name (argument="name", value=undefined, code=INVALID_ARGUMENT, version=contracts/5.8.0)

It appears that even though the configuration is provided, the internal Ocean logic is not mapping the contract addresses correctly, passing undefined to the contract factories.

const require = createRequire(import.meta.url)

@inject()
export default class DataAssetService {
  constructor(protected data_space_service: DataSpaceService) {}

    user_encrypted_key: string,

    const ethers = require('ethers')

    const user = await User.findByOrFail('uuid', user_uuid)
    const RPC_URL = 'https://rpc.test.pontus-x.eu'
    const provider = new ethers.providers.JsonRpcProvider(RPC_URL)
    
    // Wallet initialization from a custom service
    const user_wallet = await this.data_space_service.getWallet(user_encrypted_key)
    const walletWithProvider = user_wallet.connect(provider)

      .build()

    try {

      const result = await nautilus.publish(asset)

Environment
Node.js: v20+

Framework: AdonisJS v6

Library: @deltadao/nautilus

Network: Pontus-X Testnet (EVM compatible)

Question
How can I correctly inject the network configuration so that Nautilus (or the underlying ocean.js instance) recognizes the contract addresses for a non-default Chain ID? Is there a specific property I am missing for the ServiceBuilder or AssetBuilder to correctly resolve the factory addresses?
