Hey dev.to community! π
Ever had one of those bugs that makes you question your entire existence as a developer? Yeah, me too. Let me tell you about the night I almost rage-quit programming over a single word.
The Setup ποΈ
I was building a simple e-commerce app:
Frontend: React with hooks
Backend: Node.js + Express
Payment: Razorpay integration
Problem: Everything worked... except the final payment step
The Bug From Hell π
Users could browse, add to cart, fill details, but when they hit "Pay Now" - BOOM - white screen of death. No error messages, no console logs, nothing. Just a blank page laughing at my misery.
javascript// This is what I thought was working fine
const handlePayment = () => {
setLoading(true);
processPayment(paymentData)
.then(response => {
setLoading(false);
setPaymentSuccess(true);
})
.catch(error => {
setLoading(false);
setError(error.message);
});
};
The 7-Hour Journey of Despair π€
Hour 1-2: "It's probably a typo"
Checked semicolons β
Verified imports β
Cleared cache β
Still broken β
Hour 3-4: "Maybe it's the payment gateway?"
Tested API separately - worked perfectly β
Payment was processing correctly β
Money getting deducted in test mode β
UI still breaking β
Hour 5-6: "Am I even a real developer?"
Googled every variation of "react payment white screen"
Went through 47 Stack Overflow threads
Even asked ChatGPT for help - it gave me a 20-step debugging checklist
Tried every single suggestion: cleared cache, checked CORS, verified API keys, tested different browsers
All the AI suggestions were technically correct but missed the actual problem
Questioned my career choices
Considered becoming a chai vendor
Hour 7: The moment of truth
The Eureka Moment π‘
At 2 AM, completely by accident, I opened Chrome DevTools network tab and noticed something weird:
Payment request: β
200 OK
Payment response: β
Perfect
Component state: β Not updating
The response was taking ~200ms to come back, but my component was unmounting before the state could update!
The Embarrassingly Simple Fix π€¦ββοΈ
javascript// The problem
const handlePayment = () => {
setLoading(true);
processPayment(paymentData) // Missing await!
.then(response => {
setLoading(false); // This was running too fast
setPaymentSuccess(true);
});
};
// The solution
const handlePayment = async () => {
setLoading(true);
try {
await processPayment(paymentData); // Added await
await new Promise(resolve => setTimeout(resolve, 100)); // Tiny delay
setLoading(false);
setPaymentSuccess(true);
} catch (error) {
setLoading(false);
setError(error.message);
}
};
ONE MISSING AWAIT. That's it. Seven hours of my life for one word.
What I Learned π
Timing matters in UI: Sometimes components unmount before async operations complete
Network tab is your friend: Always check the actual request/response flow
AI can't debug everything: ChatGPT gave me perfect generic advice, but missed my specific timing issue
Simple bugs are the hardest: Complex problems have obvious solutions, simple problems hide in plain sight
Take breaks: After hour 4, your brain stops working properly
*Tips for Fellow Developers *π‘
When debugging async operations, always check timing
Use async/await consistently instead of mixing with .then()
Add small delays for UI state transitions if needed
Don't forget to check component lifecycle during async operations
*The Aftermath *π
When I finally saw "Payment Successful!" on the screen, I literally fist-pumped the air at 2:30 AM. Then immediately felt silly for celebrating something so basic.
But that's coding, right? Sometimes the smallest victories feel like conquering Mount Everest.
