Vercel Serverless Function Timeout - API Routes Taking Too Long
API routes that work fine locally timeout on Vercel. Long-running tasks like file processing, bulk database operations, or external API calls exceed the timeout limit.
Requests return 504 Gateway Timeout and logs show the function was killed.
Error Messages You Might See
504 - Gateway Timeout
FETCH_ERROR: request timeout
Function timeout after 30s
Vercel Serverless Function Error: timed out
Common Causes
- Function execution time exceeds timeout (default 30s, max 60s on Pro)
- Waiting for slow external API calls without timeout
- Database query not optimized or hitting connection limits
- Large file processing happening synchronously
- Missing async/await causing hanging requests
How to Fix It
Upgrade to Vercel Pro for 60s limit (free tier is 30s max)
Add timeout to external calls: fetch(url, { timeout: 10000 })
Use background jobs for long tasks - trigger async processing, return immediately
Optimize DB queries: add indexes, use pagination for large result sets
Consider moving heavy lifting to cron jobs or separate worker services

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.

’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

What's the maximum timeout on Vercel?
Free: 30s. Pro: 60s. Enterprise: up to 5min
How do I handle long-running tasks?
Trigger them asynchronously. Save a job record to DB, return immediately, process in background
Should I wait for all async tasks?
No! Return response to user, then run cleanup/processing. Use background jobs for long tasks
