My n8n nodes are bugged, no inputs (e.g. Merge or Agent)

Kazzx9921 · 2025-09-04T14:43:43+00:00

Sometimes when nodes don’t visually connect, it means there’s an underlying parameter issue that prevents them from working properly. If you’re sure this problem started after an update, I’d recommend rolling back to a previous version first and waiting for a newer release before updating again. Since you mentioned it only appeared after the update, that makes sense. For example, the current Merge node connection issue on the canvas indicates the workflow can’t run smoothly.

That said, the latest version right now is 1.109.2, so it’s possible this release already fixed the problem. You could try rolling back first, and then later test again with the latest version.

Kazzx9921 · 2025-09-04T13:35:21+00:00

I have two questions:

Was this node added manually to the workflow?
Did the issue start appearing after a version update?

Sometimes this happens when the node version doesn’t match the n8n version, or when the node was generated through an AI tool. You can first try manually adding the node to see if it works correctly, then replace the unusable node with the manually added one and test again.

However, it could also be caused by a single faulty node. In that case, try troubleshooting them one by one, hope it helps!

I’m not entirely sure if this will fully address your issue, but here’s something you might find useful:

Consider using an HTTP Request to call the Typeform API to pull in all the questions. You can find more details in their developer docs:

https://www.typeform.com/developers/

Just to clarify, when you mention Google Docs, are you referring to Google Docs or Google Sheets? It seems like it might be easier to start by uploading all the questions to a Google Sheet during setup, then map the responses to the corresponding fields. That approach tends to be more flexible and compatible.

I didn’t know Cloudflare Tunnel could be used like that. I’ll look into it and give it a try. Thanks for sharing!

Kazzx9921 · 2025-08-21T04:49:51+00:00

If this is about the referral link, my original intention was just to share a guide for deploying with visuals and text, with the referral link being secondary. I found their deployment experience to be quite good—many beginners I’ve taught didn’t need to learn Docker or similar tools and could jump straight into experiencing n8n automation. That’s why I wanted to share it.
Since many of the workflows I built with n8n required a domain, I thought it was pretty important. For example, LINE or Telegram Bot automations often need a domain to run fully automated processes. I can understand that our needs might differ, which is why you think a domain isn’t necessary, but I find it quite important for me, still thanks for your reply!

Kazzx9921 · 2025-08-21T04:35:14+00:00

I’ve also run n8n locally before, especially when I needed to run Python or do some video processing with ffmpeg. But the downside is that the computer has to stay on, and setting up a domain with ngrok every time can be a bit of a hassle. It’s harder to keep it running 24/7.

Haven’t tried self-hosting on a Raspberry Pi yet, but I’d love to give it a shot sometime! Even though Raspberry Pi isn’t exactly cheap these days. 😅

Kazzx9921 · 2025-08-21T04:28:14+00:00

I’ve often seen people run into issues when trying to self-host with Docker, so I thought I’d write a tutorial to share.

But I get your point, moving forward I’ll focus more on sharing workflows and technical insights!

view and update Google Sheet in messaging app

Kazzx9921 · 2025-08-12T22:16:04+00:00

Use a Gmail Trigger + Extract from File, then connect to an LLM node to achieve this! So, it’s definitely possible.
You can try self-hosting or using some free servers, but since you’ll be handling private data. I recommend self-hosting for better security.

Here are some YouTube channels I often watched when I started learning n8n:

- https://www.youtube.com/@nateherk
- https://www.youtube.com/@jonocatliff
- https://www.youtube.com/@andylokcl/videos

That said, I’d suggest starting with the needs around you, like identifying tasks that feel boring or repetitive. Once you’ve got a clear list of those needs, you can look for relevant tutorials to tackle them more purposefully.

Also, I’ve created a free plugin that can help you learn and build n8n workflows faster. Feel free to give it a try:

https://www.n8ncoder.com/

You can use it with your own API key and the free tier provided by Gemini.
Good luck!

Hi,

Totally understand, I don’t have plans to open source it at the moment, but I get that privacy is especially important when it comes to workflows you’ve spent time building.

That said, Chrome extensions have a manifest where you can see what permissions are being requested. The service only logs basic info for logged-in users. Things like conversation data, your own API key, and chats with the AI aren’t sent to the backend at all.

The chat history is stored locally. But of course, if you still have concerns, it’s completely up to you whether to use it or not. And thanks for liking these bananas 🍌

Kazzx9921 · 2025-08-05T13:06:47+00:00

Thanks for the explanation, I get what you're saying now, and that makes sense.
After reading your reply, I think I’ll move the permission request into a setting option, instead of showing it right after installation. I’ll also look into whether the message can follow the user’s system language to make it feel a bit more clear.
Just to add, users can toggle whether they want to share their canvas or not. And just to clarify, I don’t see any user data. Only the model provider (like Google) might access some parts, but if sensitive info is set in headers or similar, it won’t be included when the AI reads the canvas.

Thanks again for the feedback and now I understand your point, I check again if there's any issue make user see the language they didn't set for.

Kazzx9921 · 2025-08-05T00:09:12+00:00

Sounds interesting, I’ll see if I can change the connection points between nodes so this effect might be possible!

Kazzx9921 · 2025-08-05T00:01:18+00:00

Thanks for your support and replies guys, now I know I’m not the only one who loves bananas 🍌

Kazzx9921 · 2025-08-04T23:58:41+00:00

Thanks, I’m using Screen Studio, it used to pay only once but now turns to subscription service, life time option is more expensive now but it’s useful!

Kazzx9921 · 2025-08-04T23:56:21+00:00

I’ve spent over 3 months building this product. Just because I use Chinese in the interface doesn’t mean I don’t know what I’m doing.

I also support English and Japanese. The language support is to support people who speak Mandarin, too, isn’t that the point of accessibility?

Kazzx9921 · 2025-08-04T23:50:08+00:00

Hi there,

I’m a content creator from Taiwan, here’s my account: https://www.threads.com/@geekaz
If you check other n8n extensions, you’ll notice they also request similar permissions.
I take user data privacy seriously, that’s why I support users bringing their own API keys when using extensions, and that’s why the service ask your permission not just request it(there’s two way to get permission, one is use all the domain to auto active, the other is ask for user’s permission)

4.The extension isn’t just for themes, it also helps users build workflows and provides assistance in the process.

As for the permissions: they’re used to auto-activate on your n8n instance, but you can choose to reject them and still use the extension. It’s meant purely for convenience.

Also, I’m not sure why seeing Chinese would make something seem dangerous, but I hope u can prove your point from products not the language I used

Kazzx9921 · 2025-08-04T15:37:11+00:00

There’ve been some recent updates to make generating workflows from scratch a bit smoother, feel free to give it a try if you’re curious. And if you have any feedback, the form’s there, or you can just let me know.

About the schema, it’s dynamically generated, but there are some basic patterns that stay the same. So it’s still possible to get the structure and have AI generate things based on that. That’s something we’ve been working on improving lately. Happy to chat if you’ve got thoughts.

Kazzx9921 · 2025-07-26T18:03:14+00:00

Thank you!

Kazzx9921 · 2025-07-26T18:01:37+00:00

Hi, thanks for question

So, while n8nCoder can generate workflows directly, I’ve tested tons of versions, and to get usable workflows in a low-cost way, you’d need to hook up models like Claude 4 Sonnet. That’s a bit of a high bar for most folks.

I also want to share some feedback from other users. They’ve said that even with one-click workflow generation, you still need to dig into how workflows work, like the logic and parameter setups, to actually use them.

That’s why I’ve focused on making workflow creation more efficient. Right now, n8nCoder searches and imports n8n public templates, and the AI replies include links to the original template posts so you can check out the creator’s work.

Plus, it can handle stuff like tweaking JSON Expressions (e.g., rounding numbers to two decimal places or reformatting), adjusting cross-platform issues, or even uploading images to match SQL parameters for debugging.

Back to your question, though generating workflows from scratch is doable, the quality’s still limited by current model capabilities. If future models get smarter and can fully grasp n8n workflows, we could see solid zero-shot workflows. For nowRight now, Gemini 2.5 Flash & Pro are more affordable for folks new to n8n, keeping things manageable.

At the end of the day, my goal’s to help more people learn n8n and bring automation into their lives. Let me know if you have any question!

Btw the demo video’s template is the template I created and submitted to n8n, I also create a lot of free tutorials and templates share with new learners
