Sentry Error Capture

Overview

Capture errors and enrich them with structured context so your team can diagnose production issues in seconds instead of hours. Covers captureException, captureMessage, scoped context (withScope / push_scope), breadcrumbs, custom fingerprinting, and beforeSend filtering using @sentry/node v8 and sentry-sdk v2 APIs.

Prerequisites

• Sentry SDK installed and initialized (@sentry/node v8+ or sentry-sdk v2+)
• A valid DSN configured via environment variable (SENTRY_DSN)
• Understanding of try/catch (JS) or try/except (Python) error handling
• A Sentry project created at sentry.io

Instructions

Step 1 -- Capture Exceptions with Full Stack Traces

Always pass real Error objects (or Python exception instances), never plain strings. Plain strings lose the stack trace, making debugging far harder.
