How to use $env variables as entities?

[tamueller]

Hi,
I want to create a subflow that does complex logic that should be reused for different entities. I want to configure the entity in the subflow properties. I can access the properties of the subflow in other places, but I'm not sure how to choose the entity of e.g. a "call-service-node" with env-variables.
The subflow property is called "id" and I tried $env('id') $id, and{{env.id}}but I always get: "Call-service error. not a valid value for dictionary value @ data['entity_id']"

Is it possible to choose the entity during runtime somehow, if so, how?

You could add it to the data field.

{
  "entity_id": $env('id')
}

or build an input using a change/function node and pass it to the node

Thanks, I didn't know that you could override things with data or message - that's pretty helpful.
