Further Comments

I'm sending this PR because when I was trying to do backports this morning I was receiving a 404 when requesting the repo and it was missing the repo owner

[briandowns]

Can you try rancher/rke2 or k3s-IO/k3s?

[vitorsavian]

@briandowns I tried using this command here
./backport-linux-amd64 -r k3s-io/k3s -i 8033 -r 'release-1.25'
and I received
GET https://api.github.com/repos//k3s-io/k3s/issues/8033: 404 Not Found []

We could remove a / in this function if we don't wanna add another flag

func (s *IssuesService) Get(ctx context.Context, owner string, repo string, number int) (*Issue, *Response, error) {
	u := fmt.Sprintf("repos/%v/%v/issues/%d", owner, repo, number)
	req, err := s.client.NewRequest("GET", u, nil)
	if err != nil {
		return nil, nil, err
	}

	// TODO: remove custom Accept header when this API fully launch.
	req.Header.Set("Accept", mediaTypeReactionsPreview)

	issue := new(Issue)
	resp, err := s.client.Do(ctx, req, issue)
	if err != nil {
		return nil, resp, err
	}

	return issue, resp, nil
}

Removing the slash is preferred. Should be done in the lib and not the binary. I can do this today if you want.

It doesn't need to be today, I've already done the backports with the -o flag. I will close the PR.
