The core n8n workflow that pulls fresh TikTok videos and distributes them to Instagram, Twitter, Reddit, Pinterest and YouTube is already built and running on my server; what it still lacks is solid fault-tolerance. I need you to audit the existing nodes, identify every point where the scrape or upload can fail, and wrap those areas with robust error handling. Whenever any step throws an error—whether it’s a rate-limit from TikTok, a bad credential on a destination platform, or a transient network hiccup—the system should automatically retry when sensible and then notify me by email if the issue persists. Key deliverables: • Add consistent try/catch (or equivalent) logic around all critical nodes. • Configure retry logic with exponential back-off where appropriate. • Create a single error-capture flow that sends me a clear, concise email summarizing the failed step, the payload and the timestamp. • Provide brief inline documentation in n8n so I can tweak thresholds or recipients later. The project is considered complete once the workflow can run unattended for 24 hours, pushing content to all five destinations without unhandled failures and delivering readable email alerts whenever a problem is gracefully caught.
