Azure Pipeline - npm install error 403 with Azure Feed

Question

My NPM install step is configured to use registries in .npmrc,

My .npmrc is as follows

registry=https://pkgs.dev.azure.com/xxx/xxxx-xxxx-xxxx/_packaging/design-system/npm/registry/

always-auth=true

The Azure Artifacts feed is set-up, and a local npm install from my dev machine works completely fine.

However the pipeline's npm install job always fails with error 403.

What am I doing wrong here? I've also tried changing the npm install task to use Registry I select here, and linking it to my "design-system" feed directly, but it results in the same error. I've followed all the steps here https://learn.microsoft.com/en-us/azure/devops/artifacts/npm/npmrc?view=azure-devops&tabs=windows, but it just doesn't work. Thanks

Answer 1

Problem solved. What I had to do was go under into the feed -> settings -> permissions, and add the ...Build Service... as a Contributor.

Microsoft should really add this as part of their documentation. Took me several hours of random attempts before I found it..

Answer 2

This is a different solution for the same message, although, in this case it will fail from any location.

Trying to publish a package version previous to the last one published on the feed will return the 403 Forbidden error to, even if it's not a permissions issue.

Updating the package version to one increment after the current version will solve the problem.
