Integrating custom app with Databrick table

Hi Team,
Here we try to intergrate databrick from custom application.

databrickTableInsertion: async function(data){
  console.log("DAtabrick insertion db ", data.payload);

  var token = "*";
        var server_hostname = "freshworks-biz-apps-prod.cloud.databricks.com";
        var http_path = "*";
        console.log("DAtabrick insertion 1 ");

  const client = new DBSQLClient();
  console.log("DAtabrick insertion 2 ");

  client.connect(
    options = {
      token: token,
      host:  server_hostname,
      path:  http_path
    }).then(
      async client => {
        const session = await client.openSession();

        const queryOperation = await session.executeStatement(
          statement = "SELECT 1",
          options   = { runAsync: true });
          console.log("DAtabrick insertion 3 ", queryOperation);

        const result = await queryOperation.fetchAll();
        console.log("DAtabrick insertion 4 ", queryOperation);

        await queryOperation.close();
        console.log("DAtabrick insertion result 5 ", result);
        await session.close();
        await client.close();
        console.log("DAtabrick insertion result 7 ", );

        renderData(null, { "status": 200, "message": data.payload });

  }).catch(error => {
    console.log(error);
    renderData({ "status": error ? error.status : 500, "message": error }, null);

  });
}
};```

The above code is written in server.js and it is not working in our sandbox instance but working in local.
Can someone help in this?

Is the IP address mentioned in developer doc got rotated?
We have whitelisted the IP in databricks but still it does not work for us.
