Stripe webhook: TypeError on customer.id — guest checkout

Stripe sends customer: null for guest checkout events. Your handler at webhook.ts:47 calls customer.id without a null check — this started after the 11:47pm deploy added Stripe webhook validation.

ERROR TypeError: Cannot read properties of undefined (reading 'id') — webhook.ts:47

Three things Sentry
can't do.

Sentry is great at what it does. But it wasn't built for vibe coders — or for apps that run on AI.

AI reads the error for you

Sentry shows you the stack trace. DeepTracer's AI agent reads it, cross-references your logs, and writes a plain-English investigation report — automatically, in seconds.

Database pool exhausted under load

ECONNREFUSED errors spike when concurrent users exceed 40. Your db.pool.max is set to 5 — insufficient for your traffic pattern since the launch post.

Suggested fix
Set pool.max: 20 in prisma.config.ts and add connection_limit to your DATABASE_URL

Tracks your AI API costs

Your app calls GPT-4 or Claude. Those calls add up. Sentry has no idea. DeepTracer tracks every LLM call — cost, model, tokens — and alerts you before a bug burns your budget.

Monitors before errors happen

Sentry waits for errors to come to it. DeepTracer's agent proactively scans your app every 5 minutes — catching latency spikes, anomalies, and slow degradation before they become 500 errors.

Sentry is a great error tracker. DeepTracer is an AI agent that monitors your entire app — errors, logs, traces, LLM costs, and ambient health — and explains what's wrong without you having to ask.

Questions about switching

Most teams are up and running in 15 minutes.

How long does it take to switch from Sentry?

About 15 minutes. Run npm install @deeptracer/nextjs, add 5 lines to your instrumentation.ts, deploy. Your agent starts collecting data immediately.

You don't have to remove Sentry first — most teams run both in parallel for a week while they get comfortable, then drop Sentry after their first DeepTracer investigation explains something Sentry never would have.

Does DeepTracer fully replace Sentry?

For most vibe coders and small teams, yes. DeepTracer covers error tracking, log monitoring, distributed traces, LLM cost monitoring, and 24/7 ambient health — everything Sentry does plus things it doesn't.

If you specifically need Sentry's GitHub PR suggestions or its enterprise SAML SSO, you might run both briefly. But the vast majority of teams switch completely.

Do you support source maps for minified JavaScript?

Yes. Source maps are uploaded automatically during your build via the DeepTracer CLI. Investigation reports show you original source file names and line numbers — not the minified bundle.

What counts as an "event"?

Every log line, error report, trace span, or LLM call your app sends to DeepTracer counts as one event. A typical Next.js app with moderate traffic generates 10K–50K events/month. The free tier covers most side projects. Pro includes 2 million events per project per month.

What happens if my app goes viral and I hit my limit?

We never cut you off. Your agent keeps monitoring and we'll warn you at 80% and 100% of your quota. Overages are billed at $0.50 per 100K events at the end of the billing cycle. We'd rather invoice you for a good problem than go dark during your biggest day.

Is my data secure? Do you train AI on my logs?

All data is encrypted in transit (TLS) and at rest. We don't sell your data. We don't train AI models on your logs. Your data is used only to power your agent's investigations. You can delete your data at any time from your dashboard.

More questions? Email us — we typically reply same day.
