The toolCalls of ChatResponse are always empty, with no tool call information whatsoever

[anxinyh]

When SpringAI ChatClient calls a model and the model invokes a tool during execution, the toolCalls field of all elements in the returned Flux ChatResponse is empty, meaning no tool call information is returned. However, when called via SpringAI-Alibaba's ReactAgent.streamMessages, tool call information is returned.

Is this intentional design in SpringAI? If I want to retrieve tool call information from ChatResponse, what should I do?

Version: 1.1.2

This issue has been partially resolved in Spring AI version 1.1.3：

ToolCallAdvisor.builder().streamToolCallResponses(true).build()

Why only partially? Because when streamToolCallResponses is enabled, the ChatResponse only contains the tool call information and parameters, but no tool response information — meaning the ToolResponseMessage information is not added to the Flux. I'm curious: since it already supports including tool call information in ChatResponse, why isn't the response information also supported?
