ERROR: APY Connection Wordpress to N8N

Questions
1

Hi,

I Need help!

Describe the problem/error/question

I’m experiencing an issue connecting n8n to my WordPress site via the REST API. Here’s a structured overview of the problem and what I’ve tried so far:

Website

  • Domain: https://deaimeesters.com

  • WordPress version: 6.8.3

  • Plugins installed (currently all deactivated for testing): Yoast SEO, Easy Accordion, Litespeed Cache (removed), WPForms Lite, Ultimate FAQ Accordion, Popup Maker, WM Mail SMTM, WP CLI Login Command Server

n8n Setup

  • Node: WordPress

  • Resource: Post

  • Operation: Get Many

  • Credentials: WordPress Admin + Application Password + URL: (https://deaimeesters.com/wp-json/wp/v2/posts)

    Problem / Error

  • When executing the node in n8n, I receive the error:

CreateListFromArrayLike called on non-object

And

No fields - item(s) exist, but they're empty

Steps Taken So Far

  1. Deactivated all plugins to rule out plugin interference.

  2. Cleared any caches (Litespeed cache removed).

  3. Confirmed WordPress Admin user exists and an Application Password is generated for API authentication.

  4. Tested endpoint in Postman without authentication → still returns homepage HTML.

Current Status

  • Endpoint still returns the homepage HTML instead of JSON.

  • n8n cannot retrieve posts due to this issue.

Hi there!

I tried to check your restful endpoint for WordPress at deaimeesters – Zeker van je volgende stap

But getting homepage that clearly shows the issue with your htaccess rules or blocking rules with nginx or Apache you are using.

I’m really interested to look into this issue in details.

That would be nice! What do u need for info to look into it?

@Joost_Glaser
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
Add enable this in your wp-config file and then share your .htaccess}
Also I need to look into the server error log.
Also could you please confirm whether you are using nginx or apache.

For security reasons you can dm me logs here in community messaging option.
