Node 代码执行 run failed: error: operation not permitted

[yuhp-zts]

I created a workflow and want to use the output of the previous node as the input for code execution in this node. However, during debugging, the code execution node throws an error. The code in the code execution node is as follows：
def main(arg1):
from datetime import datetime, timedelta
import pytz,json
text=json.loads(arg1)
return {"text":text}

error：Node 代码执行 run failed: error: operation not permitted
the output of the previous node is ：{
"arg1": "{"start_date": "(datetime.now(pytz.timezone('Asia/Shanghai')) - timedelta(hours=5)).strftime('%Y-%m-%d %H:%M:%S')", "end_date": "(datetime.now(pytz.timezone('Asia/Shanghai'))).strftime('%Y-%m-%d %H:%M:%S')"}"
}

@yuhp-zts You imported an uninstalled dependency package, I changed the code. It works.

How to import third party dependencies? For example I want to import json5

Code execution tools have limited packages available. If you want to add a new package, I've heard that you need to modify the sandbox image, add the required package inside, and then repack it into a new image. However, I haven't actually done it myself. You can give it a try.
