        let notificationJson = req.body;
        apiClient.transaction.notification(notificationJson)

not solve dunno why, https://stackoverflow.com/questions/4816099/chrome-sendrequest-error-typeerror-converting-circular-structure-to-json , i have seen on https://github.com/Midtrans/midtrans-nodejs-client/issues/34 its work properly right ?

      let notificationJson = stringify(req.body);
      let sss = JSON.stringify({ ...req.body });
      let sssd = req.body;

      console.log(`notificationJson : ${notificationJson}`);
      console.log(`notificationJson  : ${req.body}`);
      console.log(`notificationJson  : ${sss}`);
      console.log(`notificationJson  : ${sssd}`);

Hi @yogithesymbian I don't think the issue is coming from Midtrans library. From your log the error TypeError: Converting circular structure to JSON is thrown by: node_modules/express/lib/response.js:1123:12 it is from Express library. Maybe your Express backend is unable to handle malformed HTTP response or something. Which you can check from your implementation of this line of code to know what function call produce the issue:

/src/controllers/notification.controller.js:55:26

apiClient.transaction.notification(notificationJson) will work properly if the notificationJson is a JSON object (or string) that have the correct attributes as example here: https://docs.midtrans.com/en/after-payment/http-notification?id=sample-for-various-payment-methods

From your example, the req.body value is:

[{"statusResponse":"1"},{"transaction_time":"2","no":"3"},"yogi","as"]

Which is not a valid Midtrans notification JSON.

If you want to get a valid Midtrans notification JSON to test, I suggest you setup your Sandbox account to send HTTP notification to your backend: https://docs.midtrans.com/en/after-payment/http-notification?id=configuring-http-notifications-on-map

Then perform a sandbox test payment: https://docs.midtrans.com/en/technical-reference/sandbox-test
