deleted_reply_count field always returns 0 in message objects

Stream Chat React Native: deleted_reply_count Always Returns 0

Issue Summary

The deleted_reply_count field in message objects is always returning 0, even when messages have been deleted from threads. This breaks the calculation of visible replies (reply_count - deleted_reply_count), causing incorrect UI behavior for deleted messages and thread indicators.

Expected Behaviour

When messages are deleted from a thread, the deleted_reply_count should increment accordingly, allowing proper calculation of visible replies for:

• Showing/hiding thread reply indicators on deleted parent messages
• Displaying correct reply counts in thread UIs

Actual Behavior

deleted_reply_count always returns 0, making it impossible to distinguish between threads with no replies vs threads where all replies have been deleted.

Environment Details

• stream-chat: 8.59.0
• stream-chat-expo: 6.7.2
• stream-chat-react-native-core: 6.7.2
• React Native: 0.79.5
• Expo: ~53.0.22

Code Implementation

The issue affects multiple components that rely on visible reply calculations:

// In DeletedMessageLayout.tsx and ThreadReplyIndicator.tsx
const totalReplies = message?.reply_count ?? 0;
const deletedReplies = message?.deleted_reply_count ?? 0; // Always 0
const visibleReplies = Math.max(0, totalReplies - deletedReplies);

Steps to Reproduce

1. Create a message with thread replies
2. Delete one or more replies from the thread
3. Check the deleted_reply_count field on the parent message - it will be 0 instead of the expected count
4. Thread reply indicators and deleted message UIs will show incorrect reply counts

Additional Context

• The field is properly typed in the Stream Chat TypeScript definitions as deleted_reply_count?: number
• This affects the UI logic for showing thread continuation on deleted messages
• The issue prevents proper differentiation between messages with no replies vs messages where all replies have been deleted

Impact

This bug prevents correct UI behavior for:

• Deleted message thread indicators
• Reply count displays
• Thread navigation logic for deleted messages

Type Definition Location

The field is defined in /node_modules/stream-chat/src/types.ts at line 710 in the MessageResponseBase type:

export type MessageResponseBase<
  StreamChatGenerics extends ExtendableGenerics = DefaultGenerics
> = MessageBase<StreamChatGenerics> & {
  // ... other fields
  deleted_reply_count?: number;  // This field always returns 0
  reply_count?: number;
  // ... other fields
};
