[BUG]: Express tracing errors then stops sending traces

[vernak2539]

Tracer Version(s)

5.29.0, v5.29.1, v5.30.0

Node.js Version(s)

22.11.0

Bug Report

I originally put this in #5092, but separated into it's own issue.

Since upgrading to the affected versions, we're finding that tracing stops after a bit of time. It's quite arbitrary, but it seems to be after 4-6 hours. When our application is redeployed, the tracing begins again. I've put a screenshot below to illustrate. While the screenshot shows the express.middleware operation this also happens for the express.request operation.

Versions less than the affected versions (I've tested 5.13.0, 5.21.0, 5.26.0, 5.28.0) don't seem to have this issue.

I've just enabled the logs and debug modes for our app to find out more, but initially there was no indication output as to why the tracing stopped.

I should also note that this happened in our staging and production environments. While our staging environment doesn't always have traffic, our production environment does. Additionally, both staging and production have health check endpoints that are hit by our ALBs, which should show up in tracing. During the times of no tracing, not even the health check endpoint is visible in tracing.

I've been able to find the logs, which are below. It seems the dd-trace module is encountering errors for some reason. The log:

2025-01-13T22:08:17.196Z DD_TRACE-INFO: Disabling plugin: undefined

Feels like the cause for tracing to be stopped.

Maybe it's related to #4987. But since #4987 deals with different affected versions, maybe it's different.

Note: The log Package 'next' was loaded before dd-trace! This may break instrumentation. is present in working versions. The next.request operation works fine in previous versions and in the affected versions. Our start command below which should load the instrumentation before next (we use a express custom server with next):

$ DD_TRACE_DEBUG=true DD_TRACE_LOG_FILE=ddtrace_logs.log NODE_ENV=production node --import ./src/node-instrumentation.mjs src/server/index.mjs

Reproduction Code

// ./src/server/node-instrumentation.mjs 

import tracer from 'dd-trace';

  tracer.init({
    hostname: process.env.STATSD_HOST,
    service: 'app',
    startupLogs: true,
    debug: true,
    logLevel: 'debug',
    logger: {
      error: (err) => console.error('DD_TRACE-ERROR: ', err),
      warn: (message) => console.warn('DD_TRACE-WARN: ', message),
      info: (message) => console.info('DD_TRACE-INFO: ', message),
      debug: () => {}, // (message) => console.trace('DD_TRACE-DEBUG: ', message),
    },
  });

tracer.use('express')

// ./src/server/index.mjs

import express from 'express';

const app = express()
const port = 3000

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Example app listening on port ${port}`)
})

I'm facing the same problem here. I used to use the version 5.21.0 which has a similar issue, the traces reduced significantly after 2-3 hours, and it started working again every time I restarted the container. After upgrading to the latest version 5.31.0, the issue is getting worse, there are very few traces sent to Datadog Agent :(

[souravdasslg]

Same issue! I recently updated the dd-trace to the latest version and the traces were missing in the dashboard!

[marcovr]

We are having the same issue since a few days. After a few hours of leaving our application running, the Traces (and corresponding Metrics) for express.request are dropping out and only coming back after a restart.

The application is running in the following environment:

• Container OS: Debian GNU/Linux 12 (bookworm)
• Node.js: v20.16.0

Relevant package versions:

• dd-trace: 5.30.0
• express: 4.21.2

After enabling the Tracer Debug Logs, we saw the same error Logs, e.g.:

Additionally, we can observe the following logs, but those don't seem directly related to the problem as they also appear earlier, when Traces are still being sent:

Same issue on our end. As @marcovr stated, after a few hours of leaving our application running, the traces for express.request are dropping out and only coming back after a restart.

Application Environment:

• Container OS: Amazon Linux 2023 (AL2023)
• Node.js: v22.13.0
• Relevant package versions:
  • dd-trace: 5.31.0
  • express: 4.21.2

Rolling back to dd-trace 5.28.0 seems to fix the issue.

I'm currently attempting to fix this. Please downgrade to 5.24 to avoid seeing this issue for the time being

Hey @ida613, do you have an idea of when this will be fixed? I'm not in any rush and this is just asking more for information rather than impatience. Thanks for taking a look at fixing it!

[smcgivern]

@ida613 thanks for the update, but dd-trace 5.24 is not compatible with Express 5, per @wconti27's comment at #4704 (comment).

Should we conclude from this that dd-trace's Express 5 integration is simply broken and should not be used for now?

[ida613]

@vernak2539 The change itself shouldnt take long. We have several options to solve this problem, we are discussing which one to move forward. Sorry this ticket got delayed since I was out of office, I'll keep you updated.

[ida613]

@smcgivern yes, sorry about the inconvenience!

[souravdasslg]

@ida613 , we are using Nest+Fastify! It seems like, it is broken for Fastify v5 as well!

[ida613]

We released a new version which should avoid the bug! It compromises on some baggage functionalities (i.e. not allowing the propagation of baggage without also propagating traces), but it should avoid the crash. You could give v5.36.0 a try
