Related Issues or Context

image

assistant_prompt_message.content = resp_content.replace(full_text, "", 1)

The code above attempts to simulate incremental output behavior for Dify when incremental_output=False. However, if the parameter is set to True, it may lead to undefined behavior.

As shown in the image above, the response content is initially a single backtick (`). When the next response arrives, it replaces the first occurrence of the backtick.
