Cannot log in with npm

[stephenmuss]

I am getting a 500 response from Nexus when attempting to log in using npm.

I am able to log into the Nexus web UI and also docker with my Github credentials, but npm doesn't seem to work.

I'm running Nexus Repository Manager Pro 3.9.0-01 and nexus3-github-oauth-plugin 2.0.1.

I've provided both the npm debug log and logs from the log viewer in the Nexus UI.

npm login --registry=https://nexus.myorg.com/repository/npm-repo/ --always-auth
Username: << GITHUB_USERNAME >>
Password: << GITHUB_API_TOKEN >>
Email: (this IS public) << email >>

[schmitzhermes]

Hey, are u sure u are running 2.0.1? We faced the same issue and introduced #23 as a fix. It works for us now, doesn’t it @tobilarscheid?

[tobilarscheid]

Yes, 2.0.1 was fixing exactly that.

[elntagka]

@stephenmuss did you do any special config for docker? How do you access your registry?

[stephenmuss]

@schmitzhermes @tobilarscheid yes, my bad. My ansible playbooks were telling me 2.0.1 but when I logged into the server it was still using 2.0.0. Had better run those playbooks!

Sorry for the red herring and thanks for your hard work!

@elntagka no special config apart from having to run the docker registry on a separate port as per the docs.

[tobilarscheid]

@stephenmuss would you mind publishing the relevant ansible code? I would like to link to it from the installation instructions!

[stephenmuss]

@tobilarscheid I'll see if I can find some time to publish a role to Ansible Galaxy. Cheers.

[tobilarscheid]

@stephenmuss sorry to bother you again, but does npm publish work for you? I keep getting 401 when logged in with a user created through our Github Realm.

[stephenmuss]

@tobilarscheid no, I have still been having problems with npm. Npm login works but npm install is getting 401s. I didn’t find too much helpful in the logs.

I had to create local accounts as a temporary work around.

[tobilarscheid]

Yes, exactly my issue! Really strange, it works flawlessly with local accounts - so I think there must be something to change on the plugin...

[stephenmuss]

Let me know if I can help test anything.

[tobilarscheid]

I am clueless at the moment, let's see if the sonatype guys have an idea: https://issues.sonatype.org/browse/NEXUS-16727

[leon-qin]

@tobilarscheid I have the 401 issue as well and just went through the nexus ticket you raised. Thanks for pushing sonatype guys to find the solution. Really hope this issue could be addressed soon.
