Error: Transaction hash is "NULL" while executing Privacy enabled On-chain permission (Client Lib Web3j)

[jann2005]

Description

I wanted to create a network with Privacy enabled On chain permission to execute a transaction with

Steps to re-produce - a. I have created 3 Besu nodes with privacy enabled. b. Each node is running a tressera node inside. c. --privacy-flexible-groups-enabled="true" d. Using Ethash consensus. (I have tested with CLIQE and IBFT. Its same) e. Created Privacy group with 2 participants by generating 32 bit random unique Id f . Call to create privOnChainCreatePrivacyGroup

Getting Error : Returning Transaction hash null 2022-03-01 14:46:01.800 ERROR 52874 --- [nio-8080-exec-3] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.web3j.protocol.exceptions.ClientConnectionException: Invalid response received: 400; { "jsonrpc" : "2.0", "id" : 3, "error" : { "code" : -32602, "message" : "Invalid params" } }]

Code Snippet -

    PollingPrivateTransactionReceiptProcessor processor = new PollingPrivateTransactionReceiptProcessor(
            rootBesuNode.getBesuNode(), 15000, 20);

    String txHash = rootBesuNode.getBesuNode()
            .privOnChainCreatePrivacyGroup(besuNetwork.getPrivacyGroupId(),
                    rootBesuNode.getCredential(),
                    rootBesuNode.getEnclaveKey(),
                    participantEnclaveKeyList)
            .send()
            .getTransactionHash(); //***  getResult returning NULL
    // Wait for the transaction to be mined & get the receipt
    System.out.println("Transaction hash => " + txHash);
