Publish step returns 406, but tag was pushed to repo

[brooksjbr]

I'm seeing an unexpected behavior during the publish step. I'm running a Jenkins job against Enterprise github. semantic-release is calculating the correct version based on the commit message and pushes a tag. GH responds with 406, the build fails, but the tag is successfully pushed to the repo.

What I understand 406 "Not Acceptable" to be is response given in place of a more cryptic one.
I can successfully generate and push a tag via the Jenkins job with git commands. Any ideas what the issue might be?

What GHE version is it? I’m not 100%, but a 406 response suggest a problem with the accept header I think? The request that cause the 406 is

GET https://[enterprise.company.com]/repos/[path]/[repo-name]
Accept: application/vnd.github.v3+json
User-Agent: octokit.js/16.13.3 Node.js/8.11.3 (Windows Server 2012; x64)
Authorization: token [secure]

Could you check with support@github.com if they have an idea? Send the the request above along with the GHE version

[brooksjbr]

@gr2m Thanks for the response. Will check with GH support and share what I find here.

I've also faced with this issue. In my case it was related to header handling and fixed by adding proper context path to GH_URL.
https://company.github.com → https://company.github.com/api/v3/

Has anyone contacted support about this?
https://developer.github.com/apps/building-github-apps/identifying-and-authorizing-users-for-github-apps/
Why do they have a warning and a "preview" header requirement above the "/login/oauth/access_token" endpoint?
