MS Graph API PHP SDK创建SharePoint文件夹失败求助

我参考MS Learn的示例，尝试使用MS Graph API PHP SDK在SharePoint站点中创建文件夹，代码如下：

public function createFolder($folderName)
{
    try {
        $requestBody = new DriveItem();
        $requestBody->setName($folderName);
        $folder = new Folder();
        $requestBody->setFolder($folder);
        $additionalData = [
            '@microsoft.graph.conflictBehavior' => 'rename',
        ];      
        $requestBody->setAdditionalData($additionalData);

        $response = $this->graphServiceClient->drives()->byDriveId($this->driveId)->items()->byDriveItemId("root")->children()->post($requestBody)->wait();

    } catch (Exception $e) {
        throw new Exception("Error: " . $e->getMessage());
    }
}

调用post()方法时抛出异常，返回400响应码，错误信息为：

[item] Read called with an open stream or textreader. Please close any open streams or text readers before calling Read.

已做排查：

• 通过Graph Explorer调用POST /drives/{drive-id}/items/root/children接口可正常执行，权限无问题
• PHP调用$this->graphServiceClient->drives()->byDriveId($this->driveId)->items()->byDriveItemId("root")->children()->get()->wait()能正常返回根目录下的所有项目
• 尝试在现有文件夹内创建新文件夹，仍出现相同异常

追踪ChildrenRequestBuilder内部调用流程：

ChildrenRequestBuilder.post()
-> GuzzleRequestAdapter.sendAsync()
-> GuzzleRequestAdapter.getHttpResponseMessage()
  $request = $this->authenticationProvider->authenticateRequest($requestInfo, $additionalAuthContext);
  $request->then(
    ...
    $psrRequest = $this->getPsrRequestFromRequestInformation($requestInfo, $httpResponseSpan);
    ...
  )->then(function (ResponseInterface $response)
    ...
  )

请问我哪里操作出错了？
