Expected Behavior

Dapr workflow should complete without error when the actor state store is DynamoDB.
If the value which is saved in DynamoDB state store is any binary data, save it as DynamoDB binary data type.

Actual Behavior

The following error occurs when the workflow quickstart code runs.

2025/01/10 00:05:00 failed to start workflow: failed to start orchestrator: rpc error: code = Unknown desc = error from internal actor: InternalFailure: The request processing has failed because of an unknown error, exception or failure.
== APP - order-processor ==     status code: 500, request id: 263b9cb8-2ddd-4ef1-9bcc-402853c8319c
== APP - order-processor == exit status 1
The App process exited with error code: exit status 1

This is because DynamoDB state store doesn't fully support binary data value.
When a state is saved in DynamoDB state store, the value is converted to string. If the string contains invalid UTF-8 sequences, DynamoDB throws error.

Steps to Reproduce the Problem

1. Create DynamoDB table with primary key (attribute name: key)
2. git clone https://github.com/dapr/quickstarts.git
3. Remove workflows/components/statestore_redis.yaml
4. Add workflows/components/statestore_dynamodb.yaml

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: statestore
spec:
  type: state.aws.dynamodb
  version: v1
  metadata:
  - name: region
    value: ap-northeast-1
  - name: table
    value: dapr_state
  - name: actorStateStore
    value: "true"

4. cd workflows/go/sdk
5. dapr run -f .
