Facebook登录错误PassportJS

Question

我在ExpressJS应用程序中使用PassportJS进行Facebook登录。我收到了一个以前没有遇到过的错误。

Sorry, this feature isn't available right now: An error occurred while 
processing this request. Please try again later.

{
error: {
    name: 'InternalOAuthError',
    message: 'failedtofetchuserprofile',
    oauthError: {
        statusCode: 500,
        data: '{
            "error": {
                "message": "An unexpected error has occurred. Please retry your request later.",
                "type": "OAuthException",
                "code": 2
            }
        }'
    }
}

}

我不知道为什么会收到错误。应用程序ID和密钥未更改，沙箱已禁用。
