Seeing 500s from yarnpkg.com

[glasser]

I'm seeing sporadic errors like

error An unexpected error occurred: "https://registry.yarnpkg.com/react-apollo/-/react-apollo-0.7.1.tgz: Request failed \"500 Internal Server Error\"".

They are occurring at a high enough rate to prevent me from working or deploying.

Is there a status page somewhere for issues with registry.yarnpkg.com?

[SEAPUNK]

Confirmed; our CI builds are failing because of this error.

error An unexpected error occurred: "https://registry.yarnpkg.com/@kadira/storybook-addons/-/storybook-addons-1.6.1.tgz: Request failed \"500 Internal Server Error\"".

It also looks like this can corrupt packages that are concurrently being installed. On clean caches we saw these instances. If a later version of yarn resolves this, apologies:

This seems to have cleared up, but it would really be great if there was a status page and a documented place to report outages.

[Daniel15]

I'm considering setting up a status page using Cachet (https://cachethq.io/), but I'll need to see whether the rest of the team think it's a good idea.

Apart from that, there's an open GitHub issue around having some optional logging for request failures so we can see how often they happen. I suspect the numbers that CloudFlare give us in their reports aren't capturing all the failures, so having our own data would be useful to see how often this occurs.

You can either use the --registry flag or run yarn config set registry to set a different registry mirror, for example CloudFlare's one:

yarn config set registry https://registry.npmjs.cf/

[bestander]

I agree with you @Daniel15

[blackholegalaxy]

Bug is still occuring.

[export-mike]

It seems to be happening right now.

[export-mike]

Whats strange is I request https://registry.yarnpkg.com/markdown-it-emoji/-/markdown-it-emoji-1.3.0.tgz manually and it works fine

[bestander]

Should be fixed via #2849, feel free to send a PR

[SEAPUNK]

@bestander This will only partially fix this issue. The second half of the solution should be to implement a status page for the Yarn registry for the times it really starts having problems, and the 500s don't go away on next request (which is what was happening at the time the OP was posted).

[bestander]

@SEAPUNK, that is a good idea, we already expose stats for the downloads per day https://stats.yarnpkg.com/.

According to the CDN logs we only have 100s of 500 responses a day out of 100s of millions, hopefully that fix should be good enough.
But we can take it one step further if the issue still affects people.

[glasser]

It is pretty easy to set up a status page with something like statuspage.io or status.io.

[export-mike]

As a work around use the npm registry with Yarn. https://registry.npmjs.org/

[Daniel15]

it would really be great if there was a status page

I added a status page at https://status.yarnpkg.com/ that we can use to report any major issues.

[Vanuan]

Happened approximately one hour (58-59 minutes) ago

error An unexpected error occurred: "https://registry.yarnpkg.com/@storybook/addon-links/-/addon-links-3.0.0.tgz: Request failed \"500 Internal Server Error\"".

[BYK]

This is no longer an issue so closing.

[kylemh]

@BYK I'm still receiving the same issue, even from the same package as @Vanuan

It's happened 5 times in the past month.

[vancouverwill]

@BYK seeing this multiple times today

[sortigoza]

Same issue here: error An unexpected error occurred: "https://registry.yarnpkg.com/node-gyp/-/node-gyp-3.7.0.tgz: Request failed \"500 Internal Server Error\"". :(

[OmgImAlexis]

Seeing this as well but we're also getting an issue about the signature a little further down the logs.

[matt-blanchette]

Same issue as well: [ERROR] error An unexpected error occurred: "https://registry.yarnpkg.com/read-pkg/-/read-pkg-1.1.0.tgz: Request failed \"500 Internal Server Error\"".

[justindra]

Yep, just started receiving this in our CI

 An unexpected error occurred: "https://registry.yarnpkg.com/mkdirp/-/mkdirp-0.5.1.tgz: Request failed \"500 Internal Server Error\"".

[darrendahl]

Also receiving in our CI -
error An unexpected error occurred: "https://registry.yarnpkg.com/browser-resolve/-/browser-resolve-1.11.2.tgz: Request failed \"500 Internal Server Error\""

[cice]

happening to us intermittently as well:
(at 2018-08-16 13:16:11 UTC)
error An unexpected error occurred: "https://registry.yarnpkg.com/async-each-series/-/async-each-series-1.1.0.tgz: Request failed \"500 Internal Server Error\"".

[veksen]

This happens several times a day for us. On CircleCI. I assume it's some kind of rate limiting.

[tsuna]

We started seeing those in our CI system as soon as we switching to yarn as well. If it was rate limiting then I wouldn't expect a 500 response as those are for internal errors.
