Conversation API deviating from other declarations of metadata

[qhenkart]

throughout the SDK, metadata is commonly represented by a shared object https://github.com/openai/openai-go/blob/main/shared/shared.go#L746

as seen here https://github.com/openai/openai-go/blob/main/responses/response.go#L965

And other places. This provides strict typing, shared usage and easy consumption of the SDK.

However in the conversation API, metadata is listed as any https://github.com/openai/openai-go/blob/main/conversations/conversation.go#L124 Ironically, the comment defines the exact type, but the code allows any forcing me to do type conversions like this

func toStringMap(metadata any) map[string]string {
	if metadata == nil {
		return nil
	}

	if m, ok := metadata.(map[string]string); ok {
		return m
	}

	m := map[string]string{}
	if vals, ok := metadata.(map[string]any); ok {
		for k, v := range vals {
			if s, ok := v.(string); ok {
				m[k] = s
			}
		}
	}

	if len(m) == 0 {
		return nil
	}

	return m
}
