Where the remix is deployed to lambda, I want a setup where we use sentry lambda on the server and the sentry remix on the client side. Currently, I'm getting a client._captureRequestSession is not a function whenever I call a captureException imported from @sentry/aws-serverles on remix server side (loaders/actions).

Hi @tacit pecan. I'm happy to dig into this for you! I'll check my internal sources for answers to your question! :wave:

#

Based on the knowledge sources, I can see you're encountering an issue when trying to use both Sentry Lambda and Sentry Remix together. This error typically occurs when there's a conflict between different Sentry SDKs or when they're not properly configured for your environment.

The Issue

The error client._captureRequestSession is not a function suggests there's a collision between the Node and React SDKs in your serverless environment. This happens when code intended for one environment (like Node.js) is being executed in another environment, or when multiple Sentry SDKs are initialized incorrectly.

Recommended Solution

For a Remix app deployed to Lambda, here's how you should set it up:

Server-side (Lambda) Configuration

Create an instrumentation file for your server-side SDK:

// instrument.server.mjs
import * as Sentry from "@sentry/remix";
import { AWSLambda } from "@sentry/serverless";

Sentry.init({
  dsn: "<https://examplePublicKey@o0.ingest.sentry.io/0",>
  tracesSampleRate: 1.0,
  autoInstrumentRemix: true, // For OpenTelemetry auto-instrumentation
  // Any other server-side configuration options
});

// Export the Lambda handler wrapper to use in your server entry point
export const wrapHandler = AWSLambda.wrapHandler;

Then in your server entry point:

import { createRequestHandler } from "@remix-run/architect";
import * as build from "@remix-run/dev/server-build";
import { wrapHandler } from "./instrument.server.mjs";

const handler = createRequestHandler({
  build,
  mode: process.env.NODE_ENV,
});

// Export the wrapped handler
export const lambdaHandler = wrapHandler(handler);

For handling errors in your Remix server entry point:

// entry.server.tsx
import * as Sentry from "@sentry/remix";

export const handleError = Sentry.sentryHandleError;
#

// Or if you need custom error handling:
export const handleError = Sentry.wrapHandleErrorWithSentry(
(error, { request }) => {
// Custom error handling logic
}
);


### Client-side Configuration

```javascript
// entry.client.tsx
import { useLocation, useMatches } from "@remix-run/react";
import * as Sentry from "@sentry/remix";
import { useEffect } from "react";

Sentry.init({
  dsn: "<https://examplePublicKey@o0.ingest.sentry.io/0",>
  integrations: [
    Sentry.browserTracingIntegration({
      useEffect,
      useLocation,
      useMatches,
    }),
    Sentry.replayIntegration(),
  ],
  tracesSampleRate: 1.0,
  // Other client-side configuration
});

Important Note for Vercel Deployments

If you're deploying to Vercel (which uses AWS Lambda under the hood), you'll need to use the waitUntil function to ensure Sentry events are flushed before the Lambda function completes:

import { waitUntil } from "@vercel/functions";
import * as Sentry from "@sentry/remix";

export function handleError(error: Error, { request }) {
  Sentry.captureRemixServerException(error, "remix.server", request, true);
  waitUntil(Sentry.flush());
}

This issue was specifically identified in this GitHub issue, where the Sentry team confirmed that Lambda functions on Vercel freeze on response end before Sentry has a chance to flush the data.

By following this setup, you should be able to properly integrate both Sentry Lambda and Sentry Remix in your application without encountering the client._captureRequestSession is not a function error.

@livid magnet But in remix land, would I use which captureException, sentry serverless or sentry remix? My setup is just a aws serverless deploy, no vercel.

I'm confused if I should use both together, or if the captureException from @sentry/remix will work as expected and use the instance from the instrumentation file on the serverless land.

Let me check the knowledge base for you again. One moment! :books:

Based on the knowledge sources, I can clarify which captureException method you should use in your Remix application deployed to AWS Lambda.

For a Remix app deployed directly to AWS Lambda (not via Vercel), you should use the Sentry Remix SDK for both client and server-side error capturing. Here's why:

The Sentry Remix SDK is specifically designed to handle both client and server environments in Remix applications. According to the documentation, when you initialize Sentry in your server instrumentation file, it will properly configure the SDK for the server environment:

// instrument.server.mjs
import * as Sentry from "@sentry/remix";

Sentry.init({
  dsn: "your-dsn",
  tracesSampleRate: 1.0,
  autoInstrumentRemix: true,
  // Other configuration options
});

Then in your server entry point, you should use the Remix-specific error handling functions:

// entry.server.tsx
import * as Sentry from "@sentry/remix";

export function handleError(error, { request }) {
  if (error instanceof Error) {
    Sentry.captureRemixServerException(error, "remix.server", request);
  } else {
    Sentry.captureException(error);
  }
}

For SDK versions 7.87.0 or higher, you can use the simplified approach:

export const handleError = Sentry.sentryHandleError;

For AWS Lambda specifically, you can wrap your Remix handler with the AWS Lambda wrapper from the serverless SDK:

import { createRequestHandler } from "@remix-run/architect";
import * as build from "@remix-run/dev/server-build";
import { AWSLambda } from "@sentry/serverless";
import * as Sentry from "@sentry/remix";

Sentry.init({
  dsn: "your-dsn",
  // other config
});

const handler = createRequestHandler({
  build,
  mode: process.env.NODE_ENV,
});

export const lambdaHandler = AWSLambda.wrapHandler(handler);
#

This approach is similar to what was discussed in this GitHub discussion about using Sentry with Remix when deployed to Lambda.

The key point is that you should use captureException from @sentry/remix in your Remix code (loaders, actions, components) and let the AWS Lambda wrapper handle the Lambda-specific aspects of error reporting. The Sentry Remix SDK is designed to work correctly in both client and server environments of a Remix application.

If you're experiencing issues with captureException, make sure you're properly flushing events in your Lambda environment by adding await Sentry.flush() after capturing exceptions in your server-side code.

Hope this clarifies which SDK and methods to use in your setup!

@livid magnet I see, so I can indeed use both together. I just need to use the remix packages apis in the remix land and aws serverless apis in lambda land. I imagine then that I should match their major versions? Since serverless is 9 and remix is still on latest 7.

You've identified an important issue regarding SDK version alignment. Based on the knowledge sources, you should ensure that all Sentry SDKs used in your application are on the same version to avoid compatibility issues.

SDK Version Alignment Requirement

Starting with version 8.7.0 of the Sentry JavaScript SDK, multiple Sentry SDKs on the same page will only interact with each other if they're using the same version. This is particularly relevant for your micro frontend setup where you're using both @sentry/serverless (v9) and @sentry/remix (v7).

As stated in the documentation:

For use cases like micro frontends, where you might want SDK interaction across multiple micro frontends or child applications, you'll need to ensure that all SDKs are using the same version. For example, if you initialize the SDK in a host or skeleton application, but make Sentry SDK calls (like Sentry.captureException or Sentry.setTag) in micro frontend child applications, you need to ensure that the SDK packages in the host and child applications are aligned to the same version.
JavaScript SDK Version Alignment

The error you're experiencing (client._captureRequestSession is not a function) is likely due to this version mismatch between your SDKs.

Recommended Solution

You have two options:

  1. Align SDK versions: Update both SDKs to use the same version. Since @sentry/serverless is at v9, you should upgrade @sentry/remix to v9 as well if available.
#
  1. Use a workaround: If you can't align versions, there is a workaround mentioned in the documentation, but it comes with caveats:

    If you can't get all your micro frontends aligned on the same SDK version, you can follow this workaround. However, interoperability isn't guaranteed and you could run into some unexpected behavior.

The Sentry team strongly recommends using the same version across all SDKs for the most correct behavior. As noted by a maintainer:

Although public API does not break in minor versions, improvements in instrumentation patching or event processing might be made, which is why we need to enforce this for correctness.

This version alignment requirement applies to both major and minor versions, not just major versions.

I recommend aligning your SDK versions as the first approach to resolve your issue.
