not getting real transaction ID only getting temp-transaction ID in fabric-sdk

Question

I am using below code for submitting a transaction in fabric but not getting committing transaction Id in node js SDK

       let eventHub = await hlcConnection.channel.newChannelEventHub(hlcConnection.peer);
            // eventHub =  await hlcConnection.channel.getChannelEventHubsForOrg("updevop1");
            //eventHub = await hlcConnection.channel.getChannelEventHubsForOrg();
            let txPromise = new Promise((resolve, reject) => {
                let handle = setTimeout(() => {
                    eventHub.unregisterTxEvent(transactionIdString);
                    eventHub.disconnect();
                    resolve({event_status: "TIMEOUT"});
                }, 30000);
                eventHub.registerTxEvent(transactionIdString, (tx: any, code: any, block: any) => {
                        clearTimeout(handle);
                        const returnsStatus = {event_status: code, tx_id: tx};
                        if (code !== "VALID") {
                            console.error("The transaction was invalid, code = " + code);
                            resolve(returnsStatus);
                        } else {
                            console.log("The transaction has been committed on peer " + eventHub.getPeerAddr());
                            resolve(returnsStatus);
                        }
                    }, (err: any) => {
                        //this is the callback if something goes wrong with the event registration or processing
                        reject(new Error("There was a problem with the eventhub ::" + err));
                    },
                    {startBlock: null} //disconnect when complete
                );
                eventHub.connect();
            });
            promises.push(txPromise);
