Grafana 未能创建provisioner:未能初始化文件读取器：不支持类型

我正在尝试提供一个grafana仪表板

日志上写着：

lvl=eror msg="Failed to provision dashboard" logger=provisioning error="Failed to create provisioner: Failed to initialize file readers: type is not supported"
lvl=eror msg="Stopped provisioningServiceImpl" logger=server reason="Failed to create provisioner: Failed to initialize file readers: type is not supported"

我正在尝试使用我闪亮的新仪表板—1597735961598.json标准仪表板

有什么线索吗？

经过一番努力，我发现错误是由于缺少条目类型：file引起的

我假设这是在

例如，旧版本需要此条目

apiVersion: 1

providers:
  - name: 'Default'
    type: file <-- i was missing this line 
    options:
      path: /etc/grafana/provisioning/dashboards
