Error: open /dev/null: too many open files

[dnyg]

When running a Claude LLM in Dify with the Response Format set to JSON, I receive from the langgenius/dify-sandbox:0.2.6 this error:

open /dev/null: too many open files

Hi, could you pls provide a bit more details about this? such as your DSL, logs etc.

[dnyg]

I can't really provide anything useful from the sandbox service itself, as it isn't really outputting anything. But this is how it looks from Dify:

It looks weird, I'm not sure why it costs so many times, could you pls give me your code as a testcase? you can desenstitive it of course.

@Yeuoly I have the same problem. Very simple code.

Code:

import json
import traceback

def main(body: str) -> dict:
    try:
        data = json.loads(body)['body']
        return {'result': json.dumps(data, ensure_ascii=False), 'err': ''}
    except (json.JSONDecodeError, TypeError):
        err = traceback.format_exc()
        return {'result': '', 'err': str(err)}
