Python2转Python3时pygit2推送报错KeyError：ODB类型不匹配求助

环境背景 #

• 正在将Python2代码迁移至Python3以维护单一代码库
• CPython2.7 + pygit2 0.28.2：执行推送逻辑无报错
• CPython3.10 + pygit2 1.9.2：执行推送逻辑出现错误

报错详情 #

执行代码err = C.git_remote_push(self._remote, refspecs, opts)返回错误码-3，经payload.check_error(err)映射为：
KeyError: 'the requested type does not match the type in the ODB'

完整回溯信息：

Traceback (most recent call last):
    File "/app/shared/common/git/handlers.py", line 488, in Push
        remote.push(temp3, callbacks=self.callbacks)
    File "/usr/local/lib/python3.10/site-packages/pygit2/remote.py", line 257, in push
        payload.check_error(err)
    File "/usr/local/lib/python3.10/site-packages/pygit2/callbacks.py", line 93, in check_error
        check_error(error_code)
    File "/usr/local/lib/python3.10/site-packages/pygit2/errors.py", line 56, in check_error
        raise KeyError(message)'
KeyError: 'the requested type does not match the type in the ODB'

需指引的排查方向 #

• 报错中“请求的类型与ODB中的类型不匹配”，这里的类型具体指什么？
• 是否存在pygit2版本差异：0.28.2默认启用强制推送，而1.9.2需要显式配置？
• 补充说明：Python3环境已关闭libgit2的strict mode
