Sentry Hello World

Overview

Send your first test events to Sentry — a captured message, a captured exception, and a fully-enriched error with user context, tags, and breadcrumbs — then verify each one appears in the Sentry dashboard. This skill covers both Node.js (@sentry/node) and Python (sentry-sdk).

Prerequisites

• Completed sentry-install-auth setup (SDK installed, DSN configured)
• Valid SENTRY_DSN in environment variables
• instrument.mjs loaded before app code (Node.js) or sentry_sdk.init() called (Python)
• Network access to *.ingest.sentry.io

Instructions

Step 1 — Verify the SDK Is Active

Before sending test events, confirm the SDK initialized correctly. If getClient() returns undefined, the SDK was never initialized — go back to sentry-install-auth.
