[Bug] Exception:'generator' object has no attribute 'content'

Contact Information

MaxKB Version

v2.10.2-lts

Problem Description

I define any tool in the tool, such as
tool:

def test_calc(a: int, b: int): res = a + b return { "success": True, "content": f"Calculation result: {a} + {b} = {res}" }

As long as the intelligent agent is associated, the following error is reported?
Exception:'generator' object has no attribute 'content'

Steps to Reproduce

curl http://192.168.1.1:8899/chat/api/019f128b-087b-7262-8413-e360bf021dde/chat/completions
-H "Content-Type: application/json"
-H "Authorization: Bearer agent-3a44550e80693cc309820138f5a4e78"
-d '{
"model": "deepseek-v4-pro",
"messages": [
{
"role": "旅游规划助手",
"content": "MaxKB 是什么？"
}
]
}'

The expected correct result

您好，无法复现您的问题，请提供一下您的智能体配置

我使用的是普通智能体，添加一个工具route_validator。代码如下： import json import re DISTANCE_MATRIX = { ("乌鲁木齐", "天山天池"): 1.5, ("乌鲁木齐", "S21沙漠公路"): 1, ("S21沙漠公路", "阿勒泰"): 5, ("阿勒泰", "禾木"): 3, ("阿勒泰", "布尔津"): 2, ("禾木", "喀纳斯"): 1.5, ("喀纳斯", "布尔津"): 2.5, ("布尔津", "魔鬼城"): 3, ("魔鬼城", "奎屯"): 2, ("奎屯", "赛里木湖"): 3, ("赛里木湖", "伊宁"): 2, ("伊宁", "夏塔"): 3.5, ("夏塔", "特克斯"): 2, ("特克斯", "那拉提"): 3, ("那拉提", "巴音布鲁克"): 2, ("巴音布鲁克", "独库公路"): 1, ("独库公路", "乌鲁木齐"): 5, ("那拉提", "独库公路"): 1, } # 预提取所有合法的城市/节点名称，用于快速校验 VALID_NODES = set() for start, end in DISTANCE_MATRIX.keys(): VALID_NODES.add(start) VALID_NODES.add(end) def evaluate_drive_segment(start: str, end: str, hours: float) -> str: """ 根据车程小时数，生成对应的评估提示语。 """ if hours > 8: return f"❌ {start}→{end}: {hours}小时，超过8小时上限" elif hours > 5: return f"⚠️ {start}→{end}: {hours}小时，车程较长" else: return f"✅ {start}→{end}: {hours}小时" def validate_and_calculate_route(route: str = ""): """ 工具函数：解析路线字符串，计算总车程并返回分段详情及评估。 """ try: if not route: return {"valid": False, "message": "请提供路线节点"} # 1. 健壮的路径解析 if isinstance(route, str): route = route.strip() if route.startswith("["): try: route = json.loads(route) except json.JSONDecodeError: pass if isinstance(route, str): # 【已修复】将连字符 - 移到字符集的最前面，避免被解析为范围符 parts = re.split(r"[-→,，、\s]+", route) route = [p.strip() for p in parts if p.strip()] if not isinstance(route, list) or len(route) < 2: return {"valid": False, "message": "路线格式错误，至少需要2个有效节点"} # 2. 计算车程并应用评估规则 issues = [] total_hours = 0.0 unknown_nodes = [] for i in range(len(route) - 1): start, end = route[i], route[i+1] # 预校验节点是否存在于地图中 if start not in VALID_NODES or end not in VALID_NODES: unknown_nodes.extend([n for n in [start, end] if n not in VALID_NODES]) continue key = (start, end) reverse_key = (end, start) if key in DISTANCE_MATRIX: hours = DISTANCE_MATRIX[key] elif reverse_key in DISTANCE_MATRIX: hours = DISTANCE_MATRIX[reverse_key] else: # 节点存在，但两者之间无直达路径 issues.append(f"⚠️ {start}→{end}: 无直达路径数据") continue total_hours += hours # 调用评估规则生成提示语 issues.append(evaluate_drive_segment(start, end, hours)) # 3. 返回结果 has_unknown = len(unknown_nodes) > 0 # 检查是否存在致命错误（包含 ❌ 的提示语） has_fatal_error = any("❌" in issue for issue in issues) return { "valid": not (has_unknown or has_fatal_error), "total_drive_hours": round(total_hours, 1), "issues": issues, # 包含了✅, ⚠️, ❌ 等详细评估信息 "total_nodes": len(route), "warnings": { "unknown_nodes": list(set(unknown_nodes)) if has_unknown else [] } } except Exception as e: # 兜底异常捕获，保证工具调用不崩溃 return {"valid": False, "message": f"工具内部处理异常: {str(e)}"} 关联工具后，只要使用api访问，就Exception:'generator' object has no attribute 'content' 在 2026-06-30 09:51:44，"Shenguobin0102" ***@***.***> 写道： Shenguobin0102 left a comment (1Panel-dev/MaxKB#6300) 您好，无法复现您的问题，请提供一下您的智能体配置 — Reply to this email directly, view it on GitHub, or unsubscribe.

您好，已经确认了，智能体中有技能时，必须是异步操作，stream=true 的调用方式不支持。
