Opening Incidents from AWS Lambda Failures

Send Lambda errors into TG2G so serverless incidents don't get lost.

Pattern overview

The simplest pattern is to catch unhandled errors in your Lambda and call the Event API with a structured summary. You can also wire CloudWatch alarms to TG2G, but this guide focuses on application-level events.

Node.js handler example

Lambda + Event API

const https = require("https");

function postEvent(payload) {
  return new Promise((resolve, reject) => {
    const req = https.request({
      hostname: "ingest.techguys2go.com",
      path: "/api/webhook/ingest",
      method: "POST",
      headers: {
        "X-TG2G-Api-Key": process.env.TG2G_EVENT_KEY,
        "Content-Type": "application/json"
      }
    }, res => {
      res.on("data", () => {});
      res.on("end", resolve);
    });
    req.on("error", reject);
    req.write(JSON.stringify(payload));
    req.end();
  });
}

exports.handler = async (event) => {
  try {
    // your normal logic here
  } catch (err) {
    await postEvent({
      summary: "Lambda failure: " + err.message,
      severity: "critical",
      labels: {
        function: process.env.AWS_LAMBDA_FUNCTION_NAME,
        env: "prod"
      },
      details: JSON.stringify({ error: err.message, stack: err.stack })
    });
    throw err;
  }
};
