🚨 错误信息
Function call is missing a thought_signature in functionCall parts. This is required for tools to work correctly, and missing thought_signature may lead to degraded model performance. Additional data, function call `default_api:builtin_knowledge_search` , position 2. Please refer to https://***.dev/***/***/*** for more details.

报错分析报告
1. 错误翻译
原文:Function call is missing a thought_signature in functionCall parts. This is required for tools to work correctly, and missing thought_signature may lead to degraded model performance.
译文:函数调用缺少 thought_signature 参数。这是工具正常工作的必要条件,缺少此参数可能导致模型性能下降。
2. 原因分析
根本原因:在使用函数调用功能时,请求参数中缺少必需的thought_signature 字段。
具体位置:
- 函数调用:
default_api:builtin_knowledge_search - 位置:请求中的第2个函数调用部分
- 涉及API调用或工具集成场景
问题说明:DMXAPI平台要求函数调用必须包含 thought_signature 参数,这是模型在处理工具调用时的元数据标识,用于确保函数调用的完整性和模型推理的连贯性。
3. 解决方案
方法一:修复请求参数
{
"function_calls": [
{
"name": "function_name_1",
"thought_signature": "对当前函数调用的推理思考签名",
"arguments": {...}
},
{
"name": "default_api:builtin_knowledge_search",
"thought_signature": "知识搜索函数的推理签名",
"arguments": {...}
}
]
}
方法二:使用SDK示例
// 使用DMXAPI SDK的正确调用方式
const response = await dmxapi.functionCall({
name: 'default_api:builtin_knowledge_search',
thought_signature: '用户请求需要搜索相关信息来回答',
arguments: {
query: '搜索关键词',
limit: 5
}
});
4. ️ 预防措施
最佳实践
thought_signature 字段️ 工具推荐
