Actor state cleanup onDeactivate

[bondz]

I have an actor that I used to send messages to an external party.

I have reminders and timers set in it and some state to track data I need to send.
Sometimes, the external party might be offline and not respond in the documented timeframe.

When this actor expires (deactivates), the onDeactivate callback is called.

When I try to delete the stored state in that callback or set the state to null, I get an error message.

Uncaught Error Error: {"error":"Bad Request","error_msg":"{\"errorCode\":\"ERR_ACTOR_INSTANCE_MISSING\",\"message\":\"actor instance is missing\"}","status":400}
    at execute (actors/node_modules/@dapr/dapr/implementation/Client/HTTPClient/HTTPClient.js:172:19)
    at processTicksAndRejections (internal/process/task_queues:95:5)
HTTPClient.js:172
Process exited with code 1

I have also tried to send a HTTP request to the actor state to delete the state and that also doesn't work. Is there a way to delete the actor's state when it gets deactivated?
