Troubleshooting

Video Generation Fails

Error: "Insufficient credits" or "API limit reached"

• Solution: Check your Pixverse account balance and add credits or upgrade your plan
• Prevention: Monitor credit usage and set up low-balance alerts

Error: "Prompt rejected" or "Content policy violation"

• Solution: Review Pixverse's content guidelines and revise your prompt to avoid prohibited content
• Prevention: Avoid prompts with violence, explicit content, or copyrighted material

Error: "Video generation timeout"

• Solution: Complex prompts may take longer; increase the timeout setting in the node configuration
• Prevention: Start with simpler prompts and gradually increase complexity

Caption Generation Issues

Error: "OpenAI API authentication failed"

• Solution: Verify your API key is correct and hasn't expired; regenerate if necessary
• Prevention: Store API keys securely and rotate them periodically

Problem: Captions are generic or off-topic

• Solution: Improve the prompt by including more context about the video content
• Example: Instead of {{nodes.3142.video_data}}, use:

  Create a viral TikTok caption for a video about: {{nodes.3141.PROMPT}}
  The video shows: {{nodes.3142.video_data}}
  Target audience: [your audience]
  

Problem: Missing hashtags or poor formatting

• Solution: Be more explicit in your system prompt:

  You must include exactly 5 relevant hashtags at the end.
  Format: Caption text here
  
  #hashtag1 #hashtag2 #hashtag3 #hashtag4 #hashtag5
  

Upload and Posting Failures

Error: "File upload failed" to Postiz

• Solution: Check that the video file from Pixverse is valid and accessible
• Troubleshooting steps:
  1. Verify the video URL is active
  2. Check file size limits (TikTok max: 287.6 MB)
  3. Ensure video format is supported (MP4, MOV, WEBM)

Error: "TikTok posting failed" or "Authorization error"

• Solution: Reconnect your TikTok account in Postiz
• Steps:
  1. Go to Postiz > Connected Accounts
  2. Remove the TikTok connection
  3. Re-add and re-authorize TikTok
  4. Verify posting permissions are granted

Error: "Video violates TikTok community guidelines"

• Solution: Review TikTok's content policies and regenerate with a compliant prompt
• Prevention: Avoid controversial topics, copyrighted content, or misleading information

Data Flow Issues

Problem: Variables not passing between nodes

• Solution: Check node references are correct (e.g., nodes.3141.PROMPT not nodes.3141.prompt)
• Debugging: Use the Test Node feature to inspect outputs at each step

Problem: Workflow stops mid-execution

• Solution: Check for timeout settings and increase if necessary
• Common causes:
  • Video generation taking longer than expected
  • Network connectivity issues
  • API rate limits reached

Next Steps

After Successful Setup

Immediate actions:

1. Create a content calendar: Schedule regular form submissions to maintain consistent posting
2. Build a prompt library: Document successful prompts for different content types
3. Set up monitoring: Enable workflow notifications for failures or completions
4. Track performance: Monitor which AI-generated videos perform best on TikTok

Optimization Suggestions

Improve video quality:

• Experiment with different Pixverse style settings
• Test various prompt structures to find what generates best
• Add style modifiers like "cinematic," "vibrant," or "trending"

Enhance captions:

• A/B test different caption styles (question-based, storytelling, direct)
• Analyze which hashtag combinations drive more views
• Adjust the GPT temperature setting for more or less creative output

Scale your workflow:

• Create multiple versions for different TikTok niches
• Add conditional logic to route different content types differently
• Integrate analytics to automatically track post performance

Cost optimization:

• Use gpt-4o-mini instead of gpt-4 for caption generation (already configured)
• Batch video generation during off-peak hours if Pixverse offers pricing tiers
• Monitor API usage and set budget alerts

Advanced Usage Tips

Batch processing:

• Modify the form to accept multiple prompts at once
• Add a loop node to process multiple videos in one workflow run
• Schedule bulk content creation for the week ahead

Content variations:

• Create duplicate workflows for different video styles (educational, entertainment, promotional)
• Add a node to generate multiple caption variations and select the best
• Implement A/B testing by posting slight variations and tracking performance

Quality control:

• Add a manual approval step before posting (use a webhook or Slack notification)
• Implement content moderation checks using additional AI nodes
• Create a review queue for generated videos before they go live

Integration expansion:

• Cross-post to Instagram Reels and YouTube Shorts using additional Postiz nodes
• Add analytics tracking with Google Analytics or Mixpanel
• Connect to a CRM to track which content drives conversions

Workflow templates:

• Save successful prompt patterns as reusable templates
• Create themed workflows for holidays, trends, or campaigns
• Build a library of pre-configured workflows for different content pillars
