pygit2.GitError: failed to parse supported auth schemes: The operation identifier is not valid.

Python 3.9 上で pygit2 1.10.1 と 1.12.0 をテストし、RemoteCallbacks と UserPass 認証情報を使ってプライベートな GitHub リポジトリに対する issue の clone_repository 呼び出しの失敗を再現する。traceback に示された callback と認証の経路を追跡する。原因が特定され、プライベートリポジトリのクローンに成功するか、互換性の問題が明確に文書化されれば完了とする。

I am trying to clone private github repository using pygit2 module but getting the below error.

Traceback (most recent call last):
  File ".\test2.py", line 29, in <module>
    repoClone = pygit2.clone_repository(repo_from_template.clone_url, 'C://TestRepo', callbacks=callbacks)
  File "C:\Anaconda3\lib\site-packages\pygit2\__init__.py", line 222, in clone_repository
    payload.check_error(err)
  File "C:\Anaconda3\lib\site-packages\pygit2\callbacks.py", line 93, in check_error
    check_error(error_code)
  File "C:\Anaconda3\lib\site-packages\pygit2\errors.py", line 65, in check_error
    raise GitError(message)
_pygit2.GitError: failed to parse supported auth schemes: The operation identifier is not valid.

Below is the source code I am using

import pygit2
import config_
from github import Github

g = Github(<personal access token>,base_url='https://api.github.com')
github_user = g.get_user()
org = g.get_organization(<org-name>)

repo_from_template=org.create_repo(name='TestRepo',private=True)

credentials = pygit2.UserPass(github_user.login, <personal access token>)
callbacks = pygit2.RemoteCallbacks(credentials=credentials)
repoClone = pygit2.clone_repository(repo_from_template.clone_url, 'C://TestRepo', callbacks=callbacks)

I am using python 3.9 and have tried pygit2 version 1.10.1 and 1.12.0 and both are giving the same error.
Are there any changes made to the callbacks recently which is creating this issue?
