Sentry Cookbook
Code breaks. These recipes fix it.
Recipes
Debugging undefined properties in React Native with Sentry Logs
Use Sentry Logs to determine whether an undefined property is a first-render timing issue in your React Native app or actually missing from your backend API response.
Fixing production issues in Cursor using the Sentry MCP server and Seer
Use the Sentry MCP server in Cursor to pull issues from your projects, trigger Seer root cause analysis, and apply fixes directly in your IDE — no copy-pasting stack traces required.
Monitoring your MCP server with Sentry
Wrap your MCP server with a single function call to get full visibility into client activity, transport distribution, tool and resource performance, and errors — including the silent ones MCP hides from you.
Build a performance bot with Sentry + Claude
Use Sentry span data to detect slow requests, send trace context to Claude for root cause analysis, and open GitHub pull requests with fixes — on a schedule, without anyone having to ask.
Replacing console.log with structured, trace-connected logging using LogTape and Sentry
Move from noisy string logs to structured, queryable, trace-connected events that help you debug production issues across your entire stack.
Tracking and fixing checkout performance in React Native with Sentry tracing
Instrument tracing for a React Native app with a Python backend to find slow HTTP requests in your checkout flow, fix them, and set up alerts and dashboards to stay on top of regressions.
