Hi!

Thanks now is working with daprd

In the components folder I had two files

• messagebus.yaml
• statestore.yaml

I think those files where created in the first “launch” of the extension https://github.com/microsoft/vscode-dapr and the content of the file messagebus.yaml is

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: messagebus
spec:
  type: pubsub.redis
  metadata:
    - name: redisHost
      value: localhost:6379
    - name: redisPassword
      value: ""

So after following your advice and checked $HOME/.dapr/components I renamed the

metadata:
  name: messagebus

to

metadata:
  name: pubsub

And now it’s working as expected 😃

So at the end it wasn’t a kind/bug just plain misconfiguration 😦

I will close the issue

thanks a lot

The difference between the two commands you have is that first one (which you said works), uses the default components folder which is $HOME/.dapr/components where a pubsub.yaml exists by default.

The second command uses a custom components-path, which, from the logs looks like does not have a component of type pubsub. Could you check?
