Azure DevOps - npm install task fails with 404 package not in registry

Sven Picek 21 Reputation points


I have a release pipeline containing the "npm install" task configured to use my artifact feed.
The feed has all default upstream sources set (including npmjs registry), as well as all users/groups with owner/contributor role set.
Users/groups are project collection administrators, project administrators, build administrators, build service, project collection build service and contributors,
all of which are allowed builds and releases, and project-scoped builds.

I have successfully connected to the feed from my VM and can publish my project there. Installing dependencies with "npm install package" on my VM also adds them to the feed.

As far as I can tell, everything is set up correctly, however, when running my release pipeline, it fails on the "npm install" task with the following:

As far as I can tell (but am not certain of), adding a package to my feed by installing it on the VM resolves it for that package, but I wouldn't call that a solution.
I have found several similar threads, but none of the solutions proposed there were applicable in my case.

Also, I can't seem to find relevant tags for this question. Am I asking on the wrong site?
