Package versions

npx @grafana/create-plugin@latest version
6.10.2

What happened?

I am trying to follow this example document. https://grafana.com/developers/plugin-tools/tutorials/build-a-streaming-data-source-plugin.
I have 2 issues.

• First. When implementing the example it does not work. Frontend code fails with "Query error
  Streaming channel error: invalid channel address"

• Second is that the example code in the document does not compile. Type LiveChannelAddress seems to have been changed. Property namespace in the example does not exist. There is a new property "stream".

What you expected to happen

According to the example document a datasource with streaming capabilities should be working in the loaded grafana.

How to reproduce it (as minimally and precisely as possible)

1. Ubuntu running in wsl2
   Just follow the exanple doc.
