Received malformed response from registry for undefined. When adding proxy to yarn config file

What is the current behavior?

I moved from using bower to yarn, and in my .bowerrc file I had as following:

{
    "directory": "src/main/webapp/bower_components",
    "proxy": "http://webdefence.global.blackspider.com:80",
    "https-proxy": "http://webdefence.global.blackspider.com:80"
}

And in .npmrc file I had as following :

save-prefix = ~
proprietary-attribs = false
registry = http://abc-pic:8081/nexus/content/repositories/npmjs/

So I removed these two files and I run the following commands :

yarn config set https-proxy http://webdefence.global.blackspider.com:80
yarn config set proxy http://webdefence.global.blackspider.com:80
yarn set registry http://abc-pic:8081/nexus/content/repositories/npmjs/
yarn config set proprietary-attribs false
yarn config set save-prefix ~

And then I run the following command :

yarn install --force --flat --production --modules-folder src/main/webapp/bower_components

But then I receive this error :

error Received malformed response from registry for undefined. The registry may be down.

Yarn config list

{ 'version-tag-prefix': 'v',
  'version-git-tag': true,
  'version-git-sign': false,

  'init-license': 'MIT',
  'save-prefix': '~',
  'ignore-scripts': false,

  'proprietary-attribs': false,
  'proproprietary-attribs': false,

What is the expected behavior?

yarn install works.

Please mention your node.js, yarn and operating system version.

OS : windows 7 win32 x64
node version : 5.1.0
yarn version : 1.2.1
npm version : 3.3.12

Could you also add the flag --verbose and get the output? Hopefully that will indicate what URL it is trying to hit when it reports this error.

It should end up making a request to something like "http://abc-pic:8081/nexus/content/repositories/npmjs/{package-name}" so you could pop that URL into your browser and also let us know what the registry sends back as a response.

@rally25rs This is what I got running the install with the flag --verbose :

Opening the url http://abc-pic:8081/nexus/content/repositories/npmjs/angular in the browser I get the following :

output.log

[rally25rs]

... finished with status code 503

makes it sound like the registry (or proxy) might be throwing an error when Yarn hits it.

The code that prints that message is:

if (!body['dist-tags']) {
  throw new MessageError(config.reporter.lang('malformedRegistryResponse', body.name));
}

so whatever Yarn happens to be getting back doesn't have a dist-tags property in the response body. It's quite possible that there is some difference between Yarn and the browser making the GET request, possible a different http header or something? Not really sure...

---

If you want to try debugging this, you could build yarn from the source, and inside that if statement above, add a console.log(body) and see what yarn is actually getting.

[aimad-majdou]

@rally25rs I noticed that this behavior only occurs when I set proxy and https-proxy to http://webdefence.global.blackspider.com:80 which I used in .bowerrc

[Vall3y]

This is not a solution for your bug, but you also get an error like that if you have an illegal package name (such as an empty string " ": "1.0.0")

[joshunger]

This also happens if you have a registry that can't be accessed (like only via VPN) but your internet provider returns a backup HTML page. 😃 If you want a PR let me know what you specifically want fixed.

Here is my .npmrc -

Here is curl -v -

yarn add prop-types --verbose

[knoxcard]

Prior to today yarn upgrade has always been flawless. It appears I've encountered this yarn registry bug or error, Shouldn't the default behavior error out to the console but move on and process everything else that is available?

Now is very slow without .yarnrc and yarn.lock

Rooting for you guys, don't want to go back to that stone age package manager....SAPM...aka...NPM

[echoulen]

npm is very slow too

[flewid-cd]

yes npm is also downish.

[flewid-cd]

so maybe not a yarn issue.

[EJIqpEP]

It's for sure npm issue because https://registry.npmjs.org/ is 503.
UPD: Fixed now

[vrajau]

Working again now!

[philipjc]

I just had a successful, create-react-app

[knoxcard]

NPM is still causing problems even though I've switched to Yarn? Interesting...

[flewid-cd]

@knoxcard yarn is on top of npm.

[DmitryAstafyev]

Amazing. So many things depend on one service and there is no quick way around :/ Something is wrong definitely.
Works again, but until next malfunction I guess.

[vrajau]

The day npm is definitely down, we are all doomed.

[flewid-cd]

Down again.

@flewid-cd Yarn should get beneath NPM and then rise like a Phoenix.

What is your back up strategy? npm?

I closed this issue since it diverged from the original description quite a lot. @rally25rs feel free to create a new one to track the original issue.

@joshunger Could you please tell me how to have such a cute and lovely terminal prompt？Wo~~~I like it~~~

[hayelom123]

yeah the same here

[webprogrammierer]

I have this errors using my Ubuntu VM (Drupal VM) to install packages or to run 'yarn install' and other command.
I have this errors since I have installed Docker & WSL 2 on my Windows 10 Pro.

How can those network issues be solved?

[km4dlpx]

Error: Received malformed response from registry for "webpack". The registry may be down.

I am getting this again and again, how we can solve it?

[joshuaebowling]

For anyone else who may be having this problem... for me, it turned out that a package I had installed had an empty name " ". Once I removed that reference, the packages started to flow again :)

[shadowctrl]

deleted .yarn-lock solved my issue
