Why are specific versions of npm packages not being downloaded from upstream source?

Question

We have an Azure Artifact feed with an upstream source of https://registry.npmjs.org/.

Through this Azure Artifact feed, I can download the following npm package:

• [email protected]

But I can't download the following version of the same package:

• [email protected]

If I go direct to npm (not through the artifact feed) I can pull both versions as expected.

Is there anyway to diagnose this issue further?

Answer 1

Not really sure as to why the issue happened... but I was able to solve it in my case by following these steps:

1. Navigate to "Artifacts" within Azure
2. Select your private NPM feed in the dropdown
3. Click on "recycle bin" at the top of the screen
4. Find the package which you're having trouble with
5. Click restore on the package version
