After calling privateAggregation.sendHistogram() in the reportResult() in decisionUrl code, I add the below code in my server.js file to receive duplicate debug report, which should be sent immediately based on the documentation.

app.post('/.well-known/debug/private-aggregation/report-fledge', async (request, reply) => {
  privateAggregation.enableDebugMode();
  const data = {
    query: request.query,
    body: request.body,
  };
  const log = JSON.stringify(data) + '\n';
  console.log("private reporting: "+log);
  reply.code(200);
});

However, there is nothing logged in the console. The privateAggregation.sendHistogram() should be implemented correctly in my code since I no longer received worklet errors. Did I miss anything to get the duplicate debug report?
