This issue has already been fixed by PR: #4027 you could verify it using the latest snapshot version.

4027解决的事MCPCallback，我这个问题是MethodToolCallback

Sorry, I took a closer look and it appears that the issue you mentioned was fixed by this commit: b059cdf.

spring-ai/spring-ai-model/src/main/java/org/springframework/ai/model/tool/DefaultToolCallingManager.java

Lines 195 to 199 in c2103b0

	if (!StringUtils.hasText(toolInputArguments)) {
	logger.warn("Tool call arguments are null or empty for tool: {}. Using empty JSON object as default.",
	toolName);
	finalToolInputArguments = "{}";
	}

However, similarly, this fix is not included in version 1.0.1 either, so you might still need to try the latest snapshot version.

可以先随便给个输入参数糊弄一下AI，反正返回结果是当前时间，哈哈哈。

[Caoyaya]

嗯，我是这么做的，这只是个临时解决方案，问题还是要解决的

@sunyuhan1998 帮忙看一下？

From the stack trace information you previously provided, it only shows that an error occurred when calling the LLM REST interface, but the exact cause cannot be determined. You need to add try-catch blocks around the request to capture the specific exception stack trace—namely, the failure message returned by the LLM REST interface—so that the issue can be further diagnosed.
