Are you saying the component yaml file you used is exactly the one from the docs?

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: sentinel
spec:
  type: middleware.http.sentinel
  version: v1
  metadata:
  - name: appName
    value: "nodeapp"

      ]

Please note the component is alpha, so we do not provide patch releases for Dapr to address this.

Hopefully someone has a chance to investigate this for the 1.14 release.

Sendtinel is alpha, I see
Following the tutorial docs, sentinel not work, some errors occurred
you means that the error will be fixed in the future, maybe for the 1.14 or more later

@bunengxiu right now nobody is working on or investigating this component. It might not be fixed until 1.14 or later (probably later).
