n8n Error Handling and AI-Powered Content Generation Workflow

This n8n workflow demonstrates a robust error handling mechanism combined with an AI-powered content generation and publishing system. It's designed to automatically create and publish content (likely news or articles) to a WordPress site and notify administrators via email if any part of the process fails.

What it does

This workflow automates the following steps:

  1. Error Trigger: This workflow is designed to be triggered by an error in another workflow. When an error occurs in a linked workflow, this workflow will start.
  2. HTTP Request: It then makes an HTTP request. The specific URL and method are not defined in the provided JSON, but it's likely used to fetch error details, log the error, or retrieve information related to the failed process.
  3. Edit Fields (Set): This node is used to manipulate or set data. In an error handling context, it might format the error message, extract key details, or prepare data for subsequent actions.
  4. Item Lists: This node is used for data transformation, such as aggregating, deduplicating, sorting, or splitting items. In this context, it could be used to refine a list of error messages or consolidate data before sending notifications.
  5. OpenAI: This node suggests that the workflow might leverage OpenAI's capabilities (e.g., ChatGPT, DALL-E). In an error handling context, it could be used to:
    • Summarize complex error logs into a human-readable format.
    • Suggest potential solutions or next steps based on the error description.
    • Generate a draft of an incident report.
  6. Send Email: After processing the error and potentially generating AI-driven insights, the workflow sends an email. This is crucial for notifying relevant personnel about the workflow failure, including details processed by the previous nodes.
  7. WordPress: This node indicates that the workflow can interact with a WordPress site. If this workflow is part of a larger content generation system, this node would typically publish posts, pages, or manage other WordPress content. In an error workflow, it might be used to post an internal alert or update a status page on WordPress.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Email Service (SMTP): Configured email credentials within n8n to send email notifications.
  • OpenAI API Key: Credentials for OpenAI to utilize its AI models (e.g., for summarizing errors or generating content).
  • WordPress Account: Credentials for a WordPress site if the workflow is intended to interact with it.
  • Another n8n Workflow: This workflow is designed to be an "Error Workflow" for other n8n workflows. You will need at least one other workflow configured to trigger this one on failure.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Set up your Email (SMTP) credentials in n8n.
    • Configure your OpenAI API key credentials in n8n.
    • Set up your WordPress credentials in n8n.
  3. Configure Nodes:
    • Error Trigger: This node typically requires no specific configuration as it listens for errors from other workflows.
    • HTTP Request: Configure the URL, method, and any headers/body required for your specific API call (e.g., for logging or fetching data).
    • Edit Fields (Set): Define the fields you want to set or modify based on the incoming error data.
    • Item Lists: Configure the operations you want to perform on the data (e.g., deduplicate error messages, sort logs).
    • OpenAI: Configure the specific OpenAI model and prompt you wish to use (e.g., "Summarize the following error log: {{ $json.errorData.message }}").
    • Send Email: Specify the recipient email address, subject line, and the body of the email, using data from previous nodes (e.g., {{ $json.openaiSummary }} for AI-generated summaries).
    • WordPress: If used for publishing, configure the post type, title, content, and other relevant fields.
  4. Link as Error Workflow: In your other n8n workflows, go to the workflow settings and set this workflow as the "Error Workflow" to be triggered upon failure.
  5. Activate the Workflow: Save and activate the workflow.

This setup ensures that any failures in your primary workflows are caught, processed, potentially analyzed by AI, and immediately communicated to you via email, providing a robust and intelligent error handling system.

Automated UGC video generator with Gemini images and SORA 2

This workflow automates the creation of user-generated-content-style product videos by combining Gemini's image generation with OpenAI's SORA 2 video generation. It accepts webhook requests with product descriptions, generates images and videos, stores them in Google Drive, and logs all outputs to Google Sheets for easy tracking. Main Use Cases Automate product video creation for e-commerce catalogs and social media. Generate UGC-style content at scale without manual design work. Create engaging video content from simple text prompts for marketing campaigns. Build a centralized library of product videos with automated tracking and storage. How it works The workflow operates as a webhook-triggered process, organized into these stages: Webhook Trigger & Input Accepts POST requests to the /create-ugc-video endpoint. Required payload includes: product prompt, video prompt, Gemini API key, and OpenAI API key. Image Generation (Gemini) Sends the product prompt to Google's Gemini 2.5 Flash Image model. Generates a product image based on the description provided. Data Extraction Code node extracts the base64 image data from Gemini's response. Preserves all prompts and API keys for subsequent steps. Video Generation (SORA 2) Sends the video prompt to OpenAI's SORA 2 API. Initiates video generation with specifications: 720x1280 resolution, 8 seconds duration. Returns a video generation job ID for polling. Video Status Polling Continuously checks video generation status via OpenAI API. If status is "completed": proceeds to download. If status is still processing: waits 1 minute and retries (polling loop). Video Download & Storage Downloads the completed video file from OpenAI. Uploads the MP4 file to Google Drive (root folder). Generates a shareable Google Drive link. Logging to Google Sheets Records all generation details in a tracking spreadsheet: Product description Video URL (Google Drive link) Generation status Timestamp Summary Flow: Webhook Request → Generate Product Image (Gemini) → Extract Image Data → Generate Video (SORA 2) → Poll Status → If Complete: Download Video → Upload to Google Drive → Log to Google Sheets → Return Response If Not Complete: Wait 1 Minute → Poll Status Again Benefits: Fully automated video creation pipeline from text to finished product. Scalable solution for generating multiple product videos on demand. Combines cutting-edge AI models (Gemini + SORA 2) for high-quality output. Centralized storage in Google Drive with automatic logging in Google Sheets. Flexible webhook interface allows integration with any application or service. Retry mechanism ensures videos are captured even with longer processing times. --- Created by Daniel Shashko
