@karankapur999 can you provide a reproduction case. I'm not sure how composable-middleware is used in this context.

@bizob2828

Sure , We have been using

https://www.npmjs.com/package/composable-middleware

and on invoking a function having integration with above package , it breaks

Note: This works fine on newrelic V10 and breaking on V12

👋 thank you for the report. Please provide a minimal reproducible example. Doing so will help us diagnose the issue. It should be the bare minimum code needed to trigger the issue, and easily runnable without any changes or extra code.

You may use a GitHub repository to host the code if it is too much to fit into a code block (or two).

@karankapur999 as @jsumners-nr we need a reproduction case. I cannot reproduce by doing:

const express = require('express')
const composableMw = require('composable-middleware')
const app = express()
const { PORT = 3000 } = process.env

const mw = composableMw().use(function(req, res, next) {
  console.log('in first')
  next()
}).use(function second(req, res, next) {
  console.log('in second')
  next()
})

app.use(mw)

app.get('/named-route', (req, res) => {
  res.send('hi')
})


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