创建工作流 开始 -> 执行代码 -> 结束 执行代码内容： '''def main() -> dict: from pymongo import MongoClient import json
# 连接 MongoDB
client = MongoClient("mongodb://username:password@localhost:27017/")
db = client["difydb"]
collection = db["infoCol"]
# 模拟从 Dify API 获取数据（替换为实际 API 调用）
dify_data = [
{"user": "Alice", "action": "query", "timestamp": "2025-08-20T10:00:00"},
{"user": "Bob", "action": "create", "timestamp": "2025-08-20T10:05:00"}
]
result = collection.insert_many(dify_data)
print(f"插入 {len(result.inserted_ids)} 条数据")`
然后就开始报错了；\
问题1.Failed to execute code, which is likely a network issue, please check if the sandbox service is running. ( Error: [Errno -2] Name or service not known ) \
解答1(未解决)：`services:
sandbox: image: langgenius/dify-sandbox:0.2.12 privileged: true # 解决权限问题 restart: unless-stopped # 避免无限重启循环`
config.yaml中去掉以下内容解决了sandbox重启问题，仍然出现 error: operation not permitted：
allowed_syscalls:
- "connect" - "socket" - "bind" - "listen"
- "accept" - "sendto" - "recvfrom"
问题2: pymongo.errors.ServerSelectionTimeoutError: host.docker.internal:27017: [Errno -3] Temporary failure in name resolution (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms), Timeout: 30s, Topology Description: <TopologyDescription id: 68a676d2531a846fc508af8f, topology_type: Unknown, servers: [<ServerDescription ('host.docker.internal', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('host.docker.internal:27017: [Errno -3] Temporary failure in name resolution (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms)')>]>
