AI 解决方案
报错分析报告
1.错误翻译
原文：The role only supports :`user`、`assistant` - `messages.[0]`
译文：角色仅支持：`user`、`assistant` - `messages.[0]`（即消息数组第一个元素的角色不合法）
2. 原因分析
messages数组的第1个元素（[0]）使用了API不支持的角色system，仅允许user或assistant。 messages[0].role = "system"（违反API角色约束）。3.解决方案
将
messages[0]的role改为支持的枚举值（user/assistant），或修改消息结构： {
"model": "Baichuan-M3-Plus",
"messages": [
{
"role": "user", // 将原"system"改为"user"（或"assistant"）
"content": "test"
},
{
"role": "user",
"content": "hi"
}
],
"stream": true
// 其他参数保持合法值（移除"[undefined]"）
}
4. 预防措施
messages中每个元素的role（仅允许user/assistant）。 ---
注：修复后需确保所有参数无[undefined]，补充合法值（如max_tokens设为数字）。
