知识库问答报错Tool output: Range of input length should be [1, 6000]

[denzhengwei]

使用阿里在线模型，涉及到知识库问答的时候会报错Tool output: Range of input length should be [1, 6000]

Tool input: {'query': "我是大学教授，年收入40万，无其他收入，需要交多少税”}
Tool output: Range of input length should be [1, 6000]
通过streaming=ture开启了千问的流式输出，顺便说一下文档里面llm_request:stream: true开启流式输出对千问在线模型无效

看着是给到模型的上下文长度太长，导致超过模型限制了。 可以通过combine_documents组件限制max-token方式进行约束
