How to extend timeout

This is my Python code. It is used to send network requests

```
import requests,json

API_KEY = ""
BASE_URL = "https://open.docmee.cn"

def main(taskid: str) -> dict:

url = f"{BASE_URL}/api/ppt/v2/generateContent"

payload = {
"id": taskid,
"stream": False,
"length": "short",
"lang": "zh",
# "prompt": ""
}

headers = {
"Content-Type": "application/json",
"token": API_KEY
}

try:
response = requests.post(
url,
headers=headers,
data=json.dumps(payload),
timeout=30000
)

if response.status_code != 200:
return {"result":None}

result = response.json()

if result.get("code") == 0:
markdown_text = result["data"]["text"]
return {
"result": markdown_text
}

else:
return {"result":None}

except requests.exceptions.RequestException as e:
return {"result":None}
except json.JSONDecodeError:
return {"result":None}
```

I get **Failed to parse execution result: Network or parsing error: error: timeout error: signal: killed , check sandbox service**

It seems that there is a timeout of 15 seconds. **How can I extend this timeout**

Start with the reported main function and its requests.post call, then trace how dify-sandbox handles execution timeouts for this request. Identify the setting or entry point that controls the 15-second limit and verify that a longer timeout is honored without the sandbox killing the process.
