Ensure your creative generation system runs flawlessly with these diagnostic insights and system upkeep schedules.

Common Issues & Solutions

1. Images Not Generating

Symptoms: Workflow completes, but "Generated Creatives" field is empty.

Diagnostics:

1. Check if OpenAI GPT Image model is correctly authorized (Org Verified)
2. Confirm valid image URLs are passed to GPT Image prompt
3. Look for 403 or 429 errors in HTTP Request node (rate limit or auth fail)

Solutions:

• Ensure your OpenAI account is organization-verified to access image model
• Refresh your OpenAI API key in n8n credentials
• Add wait nodes to space out image generation calls

2. Google Drive Upload Fails

Symptoms: Image generated, but not uploaded to Drive folder

Diagnostics:

1. Check n8n Google Drive node for auth/token error
2. Confirm the target folder ID exists and matches the path
3. Inspect upload file format (should be valid image URL or binary buffer)

Solutions:

• Reauthorize Google Drive integration
• Test file upload via standalone Google Drive node with dummy file
• Check MIME type and ensure correct image format (e.g., PNG/JPEG)
