Nethereum.JsonRpc.Client.RpcResponseException : The field to must have byte length of 20: eth_estimateGas

Hi, I am getting this exception when trying to estimate gas for a transaction:

Message: 
Nethereum.JsonRpc.Client.RpcResponseException : The field to must have byte length of 20: eth_estimateGas

Stack Trace:

My code snippet:
`

        // Generate a new private key
        var privateKey = EthECKey.GenerateKey().GetPrivateKey();

        // Create a new account with the generated private key
        var signer = new Account(privateKey);

        // Initialize the Web3 instances with the signer account
        var provider = new Web3(signer, Config.ETH_URL);

        var wallet = new Account(Config.ETH_KEY);

        var tx = new TransactionInput
        {
            From = wallet.Address,
            To = signer.Address,
            Value = amount.ToHexBigInteger(),
            Nonce = await provider.Eth.Transactions.GetTransactionCount.SendRequestAsync(wallet.Address),
            GasPrice = await provider.Eth.GasPrice.SendRequestAsync(),
            ChainId = await provider.Eth.ChainId.SendRequestAsync(),
            MaxFeePerGas = new HexBigInteger(875000000),
        };

        var estimatedGas = await provider.Eth.TransactionManager.EstimateGasAsync(tx);

`
My signer.Address is "0xDAf8F18fd376Eb28457baa60B7B974a2A8423bb2CCF643Eb02bF68258cdBb7a2".
My ETH_URL is "http://localhost:8545"
I am using Nethereum.Web3 Version="4.19.0"
Nethereum.Accounts Version="4.19.0"
in a .net core 7.0 app.

Adding the Request Interceptor and updating the version to 4.20.0 resolved the issue.
