 This guide demonstrates handling `DaprGrpcError` errors when using the Dapr python-SDK. It's important to note that not all Dapr gRPC status errors are currently captured and transformed into a `DaprGrpcError` by the SDK. Efforts are ongoing to enhance this aspect, and contributions are welcome. For detailed information on error handling in Dapr, refer to the [official documentation](https://docs.dapr.io/developing-applications/error-codes/).
