我正在尝试克隆 heroku 应用程序，但不断收到错误消息：
! Your key with fingerprint XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX is not authorized to access <APP NAME>.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
我试图按照这里的解决方案https://stackoverflow.com/a/9149518/79465，但没有任何帮助。
有什么想法我可能做错了吗？
