OpenAI node model get a 431 error for large inputs

Describe the problem/error/question

I experiment analyzing big documents (5-10K tokens), use gpt-3.5-turbo-1106 for that. Found out when I input such amount of text, this model shows an error:

Anyway it still works. I checked several sizes to find the breaking level. It’s somewhere around 12,000 characters. Check out two nodes below.

What is the error message (if any)?
