Matic Plasma client created, but does not initialise on mainnet

[naman-modi]

    const networkInstance = new Network(mainnet, v1);
    const matic = new MaticPlasmaClient({
      network: mainnet,
      version: v1,
      parentProvider: new HDWalletProvider(privateKey, config.parent.rpc),
      maticProvider: new HDWalletProvider(privateKey, config.child.rpc),
      parentDefaultOptions: { from: userAddress },
      maticDefaultOptions: { from: userAddress },
    });
    
    await matic.initialize();

In the above code:

• config.parent.rpc=https://goerli.infura.io/v3/........
• config.child.rpc=https://polygon-mumbai.g.alchemy.com/v2/.......
• userAddress and privateKey are correct.

The exact error:
Error: Returned values aren't valid, did it run Out of Gas? You might also see this error if you are not using the correct ABI for the contract you are retrieving data from, requesting data from a block number that does not exist, or querying a node which is not fully synced.

The matic object gets created, but initialize() does not work. Any thoughts to make it work?
(Note: the userAddress wallet has enough for Gas)
