Cursor
api
Async/Await Promise Chain Broken
After Cursor refactored your async/await code, promises are no longer resolving correctly. Operations that should happen sequentially are executing out of order, causing data inconsistencies.
Async/await syntax or promise handling was likely changed incorrectly.
Error Messages You Might See
Cannot read property of undefined
Promise rejection: undefined
Data not loaded
Operation executed out of order
Common Causes
- Missing await on async function call, continuing before completion
- Promise.all used with dependent operations (order matters)
- Try/catch removed, unhandled promise rejections
- Async function syntax broken (async not declared)
- Return statement missing in async function
How to Fix It
Always await async calls: const data = await fetchData(). Use Promise.all for parallel: Promise.all([fetch1, fetch2]). Use .then() chain for sequential. Wrap in try/catch: try { ... } catch(e) { ... }. Verify async function returns Promise.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

When should I use Promise.all?
For parallel independent operations. Promise.all(promises) waits for all. Fails if any rejects.
How do I handle async errors?
try/catch with await. Or .catch() on promise. Don't ignore errors - they'll cause bugs.
