2.6.1 - 2.6.2: build error @parcel/compressor-raw: Cannot read properties of undefined (reading 'on')
🐛 bug report
After trying to update to parcel 2.6.1 and 2.6.2, when trying to build we get an error of @parcel/compressor-raw: Cannot read properties of undefined (reading 'on') . It's an error that happens when packaging different types of files (from .js to .ico to image assets)). Everything works fine on parcel 2.6.0.
🎛 Configuration (.babelrc, package.json, cli command)
We're using the following .parcelrc:
{
"extends": "@parcel/config-default",
"transformers": {
"*.{js,mjs,jsx,cjs,ts,tsx}": [
"@parcel/transformer-js",
"@parcel/transformer-react-refresh-wrap"
]
}
}
🤔 Expected Behavior
After updating to parcel 2.6.1 or 2.6.2, build completes succesfully.
😯 Current Behavior
After updating to parcel 2.6.1 or 2.6.2, build will most of the time error with message:
Packaging index.[hash].js...
@parcel/compressor-raw: Cannot read properties of undefined (reading 'on')
On few occassions, re-running build will complete ok.
Maybe a weird dependency issue? Try deleting your lock file and node_modules and reinstalling.
If that doesn't help, please provide a reproduction.
2.6.0 working fine sounds like yet another regression of https://github.com/parcel-bundler/parcel/pull/8194 / https://github.com/parcel-bundler/parcel/pull/8235...
Can't really provide a reproduction as I'm not fully sure why it happens on our build. Attaching a screenshot of the error received. Not always the same file that throws the error and sometimes build succeeds. Tried deleting parcel cache, node modules, package-lock.json and reinstalling and trying again multiple times.
I just started a parcel project, and I'm having the same issue. I can't say the exact steps to reproduce, since, as it's happening to you, sometimes it builds, sometimes it gives me this error. However, I think it's not related to JS itself because it happens when I modify even a single letter on the main HTML file.
@mischnic Yes, I'm using Windows 10. I rolled back to 2.6.0 and no longer got this error.
I rollback parcel to version 2.6.0. I also got No Errors and it is working fine.
Just to point out that I don't think it's Windows related: I've tried this on WSL2 / Ubuntu as well, deleting all node_modules and cache and running npm install and it's the same errors. I'll try on a unix based system too, but does not seem to be related.
This is quite annoying.. and very inconsistent. I feel like when it starts to happen, if I just keep running it over and over (and getting this error over and over) it eventually fixes itself.
Running parcel 2.6.2 on Windows 10
As I've said: please say which OS you're using, and ideally share a reproduction
Looking at the offending line:
stream.on('error', err => {
reject(err);
});
The error (I think) is that stream is undefined which comes from fs.createReadStream(filePath) in the same file but I've been unable to get an undefined out of createReadStream.
I would say it's about a 50% success rate of running the build with deleting the dist folder between executions and without any code modification each time.
Is there a way to tease out the file path?
Parcel 2.6.2, Node 16.3.0, Windows 11
@andywilsonuk you could try just sticking in some console.logs in the build, directly modify the file in your node modules
There's only a handful of places where hashStream is used: https://grep.app/search?q=hashStream&filter[repo][0]=parcel-bundler/parcel
When you edit node_modules to add logging, be sure to modify the lib directory of Parcel packages, not src
Right, I think it's this commit from last month. When I follow up the stack the error is coming from line 79 in that file. Here's an example of the writeStream properties just before line 79:

It isn't always the same file but they it seems to always error on an un-optimised mp3 file > 20KB.
If it's line 79, then https://github.com/parcel-bundler/parcel/pull/8337 hopefully fixes it.
