Fix n8n Workflow: Property Listing URL → Multi-Platform Social Media Automation

I have an n8n workflow already set up on n8n Cloud that's not working properly. I need an experienced n8n automation expert to troubleshoot and fix it.

What the workflow should do:
User submits a property listing URL via password-protected web form
Fetches property page and extracts data (title, description, price, image)
Downloads and resizes property image to 1080x1080
Uses Anthropic Claude API to generate platform-specific social media posts for:

Facebook
Instagram
LinkedIn
X (Twitter)


Creates UTM tracking URLs for each platform

Has a "Publish Immediately" option:
If YES: Publishes directly to all 4 platforms
If NO: Sends preview to Telegram + logs to Google Sheets for review

Current Problem:
The workflow is built but not executing properly. Need someone to:

Diagnose why it's failing
Fix any broken nodes or connections
Test end-to-end functionality
Simplify overly complex nodes if needed

Requirements:
Work on my existing n8n Cloud instance (remote access provided)
Debug existing workflow structure
Handle errors gracefully (invalid URLs, missing images, API failures)
Simple, maintainable solution
Full testing after fixes

Deliverables:
Fixed, working n8n workflow
Documentation of what was wrong and how you fixed it
Testing guide
Brief video walkthrough of the working solution

APIs Already Configured:

Anthropic Claude API
Facebook/Instagram Graph API
LinkedIn API
X (Twitter) API
Google Sheets API
Telegram Bot API

Note: Workflow structure exists. Need someone who can quickly diagnose issues, fix broken nodes, and get it working end-to-end. Remote access to n8n instance will be provided.
