Message Interruption When Using useChat with @ai-sdk/anthropic and Asynchronous Tools, While Normal Chat Works Fine

[Abdurihim]

Description

I'm encountering an issue when using the useChat function along with @ai-sdk/anthropic in my project. The normal chat functionality seems to work without any problems. However, when attempting to use asynchronous tools within the chat, the message flow gets interrupted.

Code example

`

const result = await streamText({
  system: systemPrompt,
  model: model.model,
  temperature: 0,
  messages,
  maxTokens: model.maxTokens,
  tools,
  toolChoice: "auto",
  experimental_toolCallStreaming: true,
  maxRetries: 3,
  abortSignal: req.signal,

  onFinish(event) {
    console.log("对话结束原因:", event.finishReason);
    console.log("对话使用信息:", event.usage);
  },
  onStepFinish(event) {
    console.log("对话结束原因:", event.finishReason);
  },
});







  const {
messages,
input,
handleInputChange,
handleSubmit,
isLoading,
stop,
addToolResult,

} = useChat({
api: "/api/chat",
body: {
customData: {
developmentEnv: envSelection.developmentEnv,
selectedStack: envSelection.selectedStack,
languageModel: envSelection.languageModel,
},
},
maxSteps: 100,
async onToolCall({ toolCall }) {
console.log("onToolCall", toolCall);

  // 根据环境选择对应的工具处理器
  const handlers =
    envSelection.developmentEnv === DevelopmentEnv.ReactLive
      ? toolHandlers
      : envSelection.developmentEnv === DevelopmentEnv.Local
      ? previewToolHandlers
      : null;

  if (handlers) {
    const handler = handlers[
      toolCall.toolName as keyof typeof handlers
    ] as (args: any) => Promise<any>;
    if (handler) {
      return await handler(toolCall.args);
    }
  }
},
onError: (error) => {
  console.log("Chat error:", error);
  toast({
    variant: "destructive",
    title: "错误提示",
    description: error.message || "发生未知错误，请稍后重试",
  });
},
// 添加onFinish回调
onFinish: async (message) => {},

});
`
