在Power Automate中从SharePoint网站获取项目时，图形API错误503 serviceNotAvailable [英] Graph API error 503 serviceNotAvailable when getting item from SharePoint site in Power Automate

问题描述

我正在尝试在Power Automate中使用Microsoft Graph API，在其中我会进行呼叫以执行一些操作.我成功完成了所有Graph调用，直到出现503 serviceNotAvailable错误.

I am trying to use Microsoft Graph API in Power Automate where I make calls out to perform some actions. I have been successful with all Graph calls up to this one where I get a 503 serviceNotAvailable error.

我正在尝试拨打的电话是

The call I am trying is below

GET https://graph.microsoft.com/v1.0/groups/b40e54ac-5626-xxxx-xxxx-xxxxxxxxxxxx/drive/root:/filepath.docx

如果我将其直接粘贴到Graph API网站上的Graph Explorer中，则可以正常工作，因此我很高兴该调用在语法上是正确的.

If I paste this directly into Graph Explorer on the Graph API site it works fine so I am happy that the call is syntactically correct.

我无法通过Power Automate拨打电话.我也已经通过Postman尝试了此操作，并且遇到了同样的503错误.

I can't get the call to work through Power Automate. I also have tried this through Postman and am getting the same 503 error.

{
  "error": {
    "code": "serviceNotAvailable",
    "message": "The service is not available. Try the request again after a delay. There may be a Retry-After header.",
    "innerError": {
      "request-id": "87725851-77fb-xxxx-xxxx-xxxxxxxxxxxx",
      "date": "2020-03-01T16:55:43"
    }
  }
}

我正在拔头发...几乎什么都没有了！

Am pulling my hair out ... and there's barely anything left!

推荐答案

如果完全删除"Group.Create"权限并进行测试，它应该可以正常工作.

If you remove "Group.Create" permission completely and test, it should work.

似乎不喜欢将其与"Group.ReadWrite.All"一起使用"Group.Create"

Seems it doesn't like "Group.Create" with "Group.ReadWrite.All"
