Node Error

[Andrew_Burchfield]

Im trying to call an API. For AddEvent.com and every time (after checking all the basics) I get the following every single time. Other users have been able to successfully call the API, so why is my install different?

On Digital Ocean, running 1.73

It looks like your topic is missing some important information. Could you provide the following if applicable.

Welcome to the community @Andrew_Burchfield !

Tip for sharing information

Pasting your n8n workflow

---

Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

That implies to any JSON output you would like to share with us.

Make sure that you have removed any sensitive information from your workflow and include dummy or pinned data with it!

Could you share your workflow? And what LangChain has to do with the API call?

[Andrew_Burchfield]

How do I share the workflow? I have no idea what Lang Chain has to do. I thought it was a pretty basic API request.

[ihortom]

See the tip I shared in the previous comment. Copy the workflow (Ctrl+A to select it all and Ctrl+C to copy), then paste it in your reponse post in between the pair of triple backticks.

I believe it related to your hosting service or rather how n8n is deployed there. I ran the workflow locally and there was no issue with URL. It didn’t get the result because I do not have an account with the service. However, there is no issue sending the request to AddEvent. The HTTP Request tool itself responded with "There was an error: “Request failed with status code 401"”
