azure ad oauth令牌刷新提供错误aadsts50000

成功验证后,我想刷新我的授权令牌,因此我发出以下请求

curl -X POST \
  https://login.microsoftonline.com/<my-tenant>/oauth2/v2.0/token \
  -H 'Cache-Control: no-cache' \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -F grant_type=refresh_token \
  -F refresh_token=<my-refresh-token> \
  -F client_id=<my-client-id> \
  -F client_secret=<my-client-secret>

但是,我没有返回新的令牌,而是得到以下响应:

{
    "error": "server_error",
    "error_description": "AADSTS50000: There was an error issuing a token.\r\nTrace ID: bb72ee21-7df2-4949-8375-e6d97b621300\r\nCorrelation ID: 719ea759-622b-4d63-be17-56fd6c255195\r\nTimestamp: 2018-06-15 09:07:13Z",
    "error_codes": [
        50000
    ],
    "timestamp": "2018-06-15 09:07:13Z",
    "trace_id": "bb72ee21-7df2-4949-8375-e6d97b621300",
    "correlation_id": "719ea759-622b-4d63-be17-56fd6c255195"
}

租户、客户端ID和客户端机密都与获取刷新令牌时使用的相同。然而,有些东西显然是丢失或不正确的-但是什么?
