Cannot Get-GitHubRepository

[Liturgist]

Issue Details

This is probably just a getting started problem. What about this request is "bad"?

Steps to reproduce the issue

Hey @Liturgist,

Sorry to hear you're running into issues here. Thanks for the report.

From what you've provided, it looks like you're leveraging GitHub Enterprise, and accessing a GitHub instance running on your company's own servers. While this project has support for GitHub Enterprise (thanks to @Cellivar and @v2kiran), I've never personally used it, so I don't have any experience with it. So, I'm going to shoot in the dark here just a little bit:

1. Do you actually have a user named PowerShell in your GitHub Enterprise instance?
2. I found it interesting/confusing that the first error reported by Get-Error reported back that the server was GitHub.com, given that everything else was accessing your company's instance instead. Not sure what to take from that.
3. Do any of the other API's successfully work? (Like Get-GitHubUser -Current)?

[Liturgist]

@HowardWolosky, you are right. I did not notice that. We do have a GitHub Enterprise Server to which it appears to be connecting. How can I tell it to connect to the public github.com?

I removed the GH_HOST environment variable.

I used the EXAMPLE 5 command, but it still appears to be connecting to our GitHub Enterprise Server. The Personal Access Token used was created on the public github.com.

PS C:\Users\pwatson2> Get-GitHubRepository -Uri https://github.com/microsoft/PowerShellForGitHub
Invoke-WebRequest: C:\Users\lit\Documents\PowerShell\Modules\PowerShellForGitHub\0.16.1\GitHubCore.ps1:313
Line |
 313 |              $result = Invoke-WebRequest @params
     |                        ~~~~~~~~~~~~~~~~~~~~~~~~~

[HowardWolosky]

How can I tell it to connect to the public github.com?

The README talks about how to configure GitHub Enterprise. You'll probably want to run this:

Set-GitHubConfiguration -ApiHostName 'github.com'

That should reset it to use public GitHub instead of GitHub Enterprise. Alternatively, you can run this:

Reset-GitHubConfiguration

and that will get you back to the out-of-the-box state (in case you might have messed with other configuration properties accidentally).

I removed the GH_HOST environment variable.

This project doesn't use any environment nor global variables. Everything is self-contained in the module configuration.

I used the EXAMPLE 5 command, but it still appears to be connecting to our GitHub Enterprise Server

Yeah, that wouldn't work. When you use the Uri parameter, it just parses the OwnerName and RepositoryName from the Uri, and then operates against the configured GitHub host to get the requested info. If you want to operate against the public GitHub.com, you need to fix your ApiHostName.

[Liturgist]

@HowardWolosky, yes, I can see how the ApiHostName would be a problem. I have reset it as yo recommended. It now appears to be github.com. I still have the same failure, but only github.com is mentioned and not out GitHub Enterprise Server. What am I missing?

This does work as expected on my personal machine that is not on the corporate network.

I still have the same failure, but only github.com is mentioned and not out GitHub Enterprise Server. What am I missing?

This does work as expected on my personal machine that is not on the corporate network.

All I can suggest is a complete reset of everything:

Reset-GitHubConfiguration
Clear-GitHubAuthentication

and then trying an unauthenticated command

Get-GitHubRepository -OwnerName microsoft -RepositoryName PowerShellForGitHub

That request will work unauthenticated (just verified again). If it still doesn't work, and it's working fine on your personal machine, then that means that your corporate machine is running through a proxy that is modifying the REST request and causing it to fail. If that does work, then you can try adding back in your token and we can further debug what's happening from there.

[Liturgist]

Many thanks @HowardWolosky. It is working now. Although, I do not understand why it did not work when I used Reset-GitHubConfigration before. I will press on. Thanks.
