dapr: Mongodb state-store not working

When creating/configuring the state-store as mongodb, writing and initializing works correctly, but when trying to read some information from the state-store, a serialization error occurs.

Another point, when comparing the creation of the actors’ reminders partitions in other databases, such as PgSQL, in mongo db, every time the application is restarted, more N partitions of the reminders are created

Expected Behavior

Return state-store information

Actual Behavior

Exception when trying to deserialize information

[18:06:10 ERR] An unhandled exception has occurred while executing the request.

Steps to Reproduce the Problem

Change the state-store host/server on “dapr/components/daprmongodbbug-statestore.yaml” I’ve attached an example ASP.Net core project, just run docker-compose (note there is a docker compose override)

Execute the sample project running the docker-compose, Navigate to: http://127.0.0.1:5200/swagger/index.html Execute the endpoint: createActor sending some paramters on model ( the field id is the actor id ) After this, try to read the actor details on the “GET” endpoint
