Good to see this project, I will trace the duplicate trigger firing in your N8N middleware, fix the root cause, and document every change with inline comments so you can maintain it yourself. The first thing I will check is whether the trigger node lacks a deduplication key or if a downstream branch is looping back and re-activating it. I will test the corrected workflow on your staging instance before touching anything live. One question: is the trigger webhook-based, or is it a polling/cron trigger? Looking forward to talking through the details. Kamran

Hi there, I can already see the hidden issue: your middleware is letting the event re-enter the flow, so the trigger behaves like it’s echoing itself. I’ve worked on N8N workflows where one small loop or webhook retry caused duplicate runs, and I’ll trace the exact node path, fix the middleware logic, and keep the final solution fully importable inside N8N. I’ll review your .json export, inspect the execution pattern in the built-in debugger, and use the Loom walkthrough to pinpoint why the trigger is firing more than once. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I’ll also leave a short changelog so the workflow is easy to maintain later. If credentials are ready, I can start with the current export and return a cleaned version plus notes on what changed. Could you share whether the duplicate firing happens on every event or only specific middleware branches? Best regards, Asad

Hello, I understand you're experiencing issues with your N8N workflow where the trigger is firing multiple times instead of once per event. This is a common challenge that can disrupt the functionality and flow of your virtual agent. To address this, I will dive into the middleware logic to identify and resolve the root cause of these repetitive trigger firings. Utilizing my expertise in AngularJS, JavaScript, and Node.js, I will thoroughly examine the API integration and existing architecture. By testing various scenarios and debugging, my aim is to identify and rectify the logic errors causing this problem. Moreover, I'll ensure robust error handling is in place to prevent similar issues in the future, thereby stabilizing the workflow. Let's work together to streamline your virtual agent's performance.

Hello Your n8n virtual agent throwing workflow errors usually means a failed node execution, data mismatch, or API timeout. I can help debug this. I regularly build and troubleshoot complex n8n workflows, recently fixing a similar agent issue by restructuring its error-handling and JSON parser nodes. Let’s check your execution logs and get it running smoothly again. Can you share a screenshot of the failing node? Giáp Văn Hưng

@DeveloperStation

Hi, I’ve developed multiple N8N workflows that integrate with various APIs and services, including Google, HubSpot, and Stripe. I’ve also worked extensively with Node.js and TypeScript, which are essential for debugging and fixing issues in N8N. In your case, the problem could stem from multiple areas, such as the trigger firing multiple times or the middleware logic not handling events correctly. I’d start by checking the trigger and then move on to the middleware logic. I can also add some logging to help identify the root cause more quickly. Let’s schedule a 10-minute introductory call so I can learn more about your project and we can discuss the approach in detail. I usually respond within 10 minutes. I’m eager to hear more about your exciting project. Best regards, Adil

Looking at your SDR agent, the repeated firing almost certainly isn't the trigger — it's the Redis buffer in your middleware. That block is supposed to collect the rapid WhatsApp messages and pass only the last one to the agent, but when the "am I the final message?" check races the TTL, several slip through and the agent runs multiple times per conversation. I'd replay your .json against staging and watch the buffer node in the debugger to see which execution actually reaches the agent. Then I'd scope the buffer key per contact, make the wait-and-compare step atomic, and drop stale executions instead of forwarding them — with inline notes so you can maintain it after. I've built debounced messaging like this on an Express backend before, so it's familiar ground. Is the Evolution API node installed on staging, or should I plan around it being missing? Happy to jump in once you're set.

Hi there, This sounds like a workflow control issue where the middleware path is allowing the same event to re-enter or pass through more than once. I can review the exported n8n JSON, reproduce the duplicate trigger in staging, and trace the execution path with the n8n debugger. My approach would be to isolate the trigger, inspect the branching and middleware conditions, then adjust the workflow so each event has a single clear execution path. I’ll keep the fix inside n8n, without adding outside services or dependencies. I’ve handled similar event-driven and automation issues in Node.js-based systems where duplicate execution caused downstream errors, so I’ll also leave a short changelog or comments to make the fix easy to maintain. Please send the JSON export and Loom when ready, and I can confirm the exact fix path. Regards, Zahid

@C0RETECHIES

Hi there, It sounds like your n8n virtual agent is processing a single event, but the middleware logic is causing a re-entrant condition or loop, firing the main workflow multiple times. This usually points to a missing idempotency check, where the system fails to recognize it has already processed that specific event. Technical approach: I'll use the n8n debugger to trace the data flow from the trigger. The fix will likely involve implementing a conditional gate (using an If/Switch node) that checks a unique event identifier. This ensures the primary logic branch executes only once per unique event, preventing any duplicate runs. Core modules: The corrected workflow will consist of three clear stages: Event Ingestion (the trigger), an Idempotency Gate (the new validation logic), and the final Action Processing branch. This isolates the fix and makes the flow's state management clear. Relevant systems: We've engineered many n8n automations where execution control is critical. For instance, our AI Slack Assistant uses logic gates to prevent duplicate workflow runs from a single user message, and our Sales Call Automation requires strict idempotency to avoid re-contacting leads. I'll start by reviewing the Loom video and JSON to replicate the bug. After isolating the node causing the issue, I'll implement the fix, run multiple tests to confirm single execution, and document the changes in the workflow file itself. Regards, Rohit
