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

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?

Reproduzca el fallo de la llamada clone_repository del issue usando RemoteCallbacks con credenciales UserPass contra un repositorio privado de GitHub en Python 3.9, probando pygit2 1.10.1 y 1.12.0. Siga la ruta de callback y autenticación indicada por el traceback; el trabajo estará terminado cuando se identifique la causa y el clonado privado funcione, o cuando la incompatibilidad esté documentada claramente.
