Wordpress post not working

Hi, I am a new N8N self hosted user, and wanting to post some data from a filemaker db to a new wordpress post (both hosted on my Synology NAS on a fixed IP). N8N in container manager, filmmaker server in ubuntu VM.

When I set up the connections to both systems, the sign in is successful. Filemaker returns the field I want (a temperature value), but when I try to post to Wordpress as a new post, it fails. As I say, the connection to wordpress works fine.

I get the following error - which is beyond my understanding - I am a basic/intermediate user:

}

Hoping someone may either have had a similar issue which they fixed, or that they might understand the error stuff!

Many thanks in advance!

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

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Welcome to the community @wiz01 !

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!


The error indicates that you have successfully connected but the user you used to connect has no permissions to create a post (in the specified lication at least). You would have to check your user permissions on Wordpress side.
