Steps to reproduce

The following is the content replied by the agent

我需要提供一个完整的 HTML 文件，包含粒子效果。我将使用 JavaScript 和 CSS 来实现这个效果。

@Lz020316 Hello there! I'm here to help you with any bugs, questions, or contributions you have in mind. Let's tackle this issue together while we wait for a human maintainer.

Dify currently does not support embedding interactive HTML content, such as the HTML file with JavaScript and CSS for particle effects, in its LLM response box. This limitation means that attempts to include such content in agent responses will likely result in parse errors or unexpected behavior [1].

To address this, consider providing a link to an external resource where the HTML content can be viewed or executed, or simplify the response to exclude interactive elements.

To continue talking to Dosu, mention @dosu.

I think this problem can be solved. It's currently in the market, chatgpt，Claude， There are still many model platforms that support replying to HTML language. I don't think there should be a situation where it displays as empty, which is a bug. Another issue is that the markdown language supports HTML language, for example

Hi, @Lz020316. I'm Dosu, and I'm helping the Dify team manage their backlog. I'm marking this issue as stale.

Issue Summary

  • You reported a parse error when generating a complete HTML file with particle effects in Dify version 0.11.1.
  • The issue occurs on a self-hosted Docker setup.
  • I mentioned that Dify doesn't support embedding interactive HTML in its LLM response box.
  • You noted that other platforms support HTML responses and provided a code snippet, suggesting this might be a bug.

Next Steps

  • Please confirm if this issue is still relevant to the latest version of the Dify repository. If so, you can keep the discussion open by commenting here.
  • If there is no further activity, this issue will be automatically closed in 15 days.

Thank you for your understanding and contribution!
