Steps to reproduce

Dear DIFY Team,

Fault Description: When DIFY outputs content, if the content is too long, the text and formatting at the end become uncontrollable (such as repetition, garbled text, excessive spacing, and other anomalies).

Reproduction Steps: Initially, I suspected it was an issue with the capabilities of the gpt-4o model. However, when I imported the same knowledge document into both DIFY and FASTGPT and requested both to output all content from the knowledge base (or a specific point, as long as there is enough content), I found that: FASTGPT's output was normal, but DIFY's output was abnormal.

So, I conducted a second round of testing:

I integrated the normal output from FASTGPT as an API into DIFY's workflow (using DIFY's HTTP request module). I disabled DIFY's own knowledge base and directly used the FASTGPT API via HTTP requests. At this point, I found that the FASTGPT API output was normal, but the content transmitted to DIFY still exhibited the aforementioned anomalies.

---

"I have to add that this is not just a web rendering issue. By using the workflow mentioned above, I published DIFY as an application and queried it through the DIFY API with the same long text content. I also encountered formatting issues, typos, and other anomalies as described above."

Look forward to your reply, thank you!
