Original Pull Request: https://github.com/langgenius/dify/pull/30717

State: closed
Merged: Yes

Reverts langgenius/dify#30651

The original fix seems correct on its own. However, for chatflows with multiple answer nodes, the message_replace command only preserves the output of the last executed answer node.

The follow DSL is an example:
