Overview

Automatically send errors and source maps to your Sentry project from your Trigger.dev tasks. Sending source maps to Sentry allows for more detailed stack traces when errors occur, as Sentry can map the minified code back to the original source code.

​
Prerequisites

​
Build configuration

To send errors to Sentry when there are errors in your tasks, you’ll need to add this build configuration to your trigger.config.ts file. This will then run every time you deploy your project.
You will need to set the SENTRY_AUTH_TOKEN and SENTRY_DSN environment variables. You can find the SENTRY_AUTH_TOKEN in your Sentry dashboard, in settings -> developer settings -> auth tokens and the SENTRY_DSN in your Sentry dashboard, in settings -> projects -> your project -> client keys (DSN). Add these to your .env file, and in your Trigger.dev dashboard, under environment variables in your project’s sidebar.
trigger.config.ts
import { defineConfig } from "@trigger.dev/sdk";
import { esbuildPlugin } from "@trigger.dev/build/extensions";
import { sentryEsbuildPlugin } from "@sentry/esbuild-plugin";
import * as Sentry from "@sentry/node";

export default defineConfig({
  project: "<project ref>",
  // Your other config settings...
  build: {
    extensions: [
      esbuildPlugin(
        sentryEsbuildPlugin({
          org: "<your-sentry-org>",
          project: "<your-sentry-project>",
          // Find this auth token in settings -> developer settings -> auth tokens
          authToken: process.env.SENTRY_AUTH_TOKEN,
        }),
        { placement: "last", target: "deploy" }
      ),
    ],
  },
  init: async () => {
    Sentry.init({
      defaultIntegrations: false,
      // The Data Source Name (DSN) is a unique identifier for your Sentry project.
      dsn: process.env.SENTRY_DSN,
      // Update this to match the environment you want to track errors for
      environment: process.env.NODE_ENV === "production" ? "production" : "development",
    });
  },
  onFailure: async ({ payload, error, ctx }) => {
    Sentry.captureException(error, {
      extra: {
        payload,
        ctx,
      },
    });
  },
});
Build extensions allow you to hook into the build system and customize the build process or the resulting bundle and container image (in the case of deploying). You can use pre-built extensions or create your own.

​
Testing that errors are being sent to Sentry

To test that errors are being sent to Sentry, you need to create a task that will fail. This task takes no payload, and will throw an error.
trigger/sentry-error-test.ts
import { task } from "@trigger.dev/sdk";

export const sentryErrorTest = task({
  id: "sentry-error-test",
  retry: {
    // Only retry once
    maxAttempts: 1,
  },
  run: async () => {
    const error = new Error("This is a custom error that Sentry will capture");
    error.cause = { additionalContext: "This is additional context" };
    throw error;
  },
});
After creating the task, deploy your project. 
npx trigger.dev@latest deploy
Once deployed, navigate to the test page in the sidebar of your Trigger.dev dashboard, click on your prod environment, and select the sentryErrorTest task. Run a test task with an empty payload by clicking the Run test button. Your run should then fail, and if everything is set up correctly, you will see an error in the Sentry project dashboard shortly after.
