Need to add support for tracing.
@ancalita I might need your help on this one.

Yeah we will need to update the code on rasa-private side too to inject the trace context in the grpc request. I am searching for some docs / looking in opentelemetry to see if there's any guidance.

Couldn't find any guidance I'm afraid :(

I'll try to look it up.

@ancalita I added tracing for GRPCActionServerWebhook.Webhook.

Same question here about not using the method args as above. Also context is missing type hint.

I tried but I could not find the type of the context anywhere.
Considering method args, this is the cleanest way to do it according to protobuf docs.
It provides good options for backwards compatibility later on.

Found the type of context after some digging through docs. It's grpc.aio.ServicerContext.

This had the WebhookRequest before I think in the typing hint, could you please re-add it?

No need. I create tracer in GRPCActionServerWebhook.Webhook.

But that serves a different purpose, we need this for passing the rasa-private context to the sdk 🤔

The tracer in the webhook instruments the webhook separately.
Add support to communicate with Rasa over gRPC protocol.
