Steps to reproduce

1、When I run the tool using the code, I encounter an error when using re for information extraction. It works fine during debugging, where I use the output from the previous step as the input.：
raceback (most recent call last): File "/tmp/code/80dd75ff_2d72_4367_a334_5e133f5650e5.py", line 63, in File "/tmp/code/80dd75ff_2d72_4367_a334_5e133f5650e5.py", line 53, in main IndexError: list index out of range error: exit status 255

2、The output from the previous step is as follows.
{
"arg1": "python\n{\n \"keyWord\": \"\",\n \"customerSource\": \"\",\n \"customerType\": \"\",\n \"belongDistrict\": 860,\n \"industry\": \"\"\n}\n\n\n由于提示信息中并没有提供具体的keyWord（公司简称）、customerSource（客户层级）和customerType（客户类型），所以这些字段对应的值设为空字符串。而belongDistrict（所属地区id）可以根据提示2中的最高score（这里假设分数由数字部分决定，即ID的数值大小）来确定，因此取ID为860的“上海市”作为所属地区。提示信息中并未包含industry（所属行业id）的相关内容，故该字段也设为空字符串。",
"czr": 16073
}

3、 Below is the code for parsing the arg1 parameter:
import json
import re
def main(arg1,czr) -> dict:
pattern = r'{.*?}'
arg2 = re.findall(pattern, arg1)

return {
    "query_input":arg2[0]
}

4、
Debugging is normal：

but there is an error when running

The IndexError: list index out of range error you're encountering is likely due to the re.findall function not finding any matches in the arg1 string, resulting in an empty list. When you try to access arg2[0], it raises an IndexError because the list is empty.

To handle this, you can add a check to ensure that arg2 is not empty before accessing its elements. Here's an updated version of your code:

import json
import re

def main(arg1, czr) -> dict:
    pattern = r'{.*?}'
    arg2 = re.findall(pattern, arg1)
    
    if not arg2:
        return {
            "query_input": "No match found"
        }
    
    return {
        "query_input": arg2[0]
    }

This code will return a message indicating that no match was found if re.findall returns an empty list, preventing the IndexError.

Additionally, ensure that the input string arg1 is correctly formatted and contains the expected pattern. If the input format varies, you might need to adjust the regular expression pattern accordingly.

Is this the solution to this problem?

I would like to clarify this have you publish the application for the new workflow?

The IndexError: list index out of range error you're encountering is likely due to the re.findall function not finding any matches in the arg1 string, resulting in an empty list. When you try to access arg2[0], it raises an IndexError because the list is empty.

As the bot's said, I think there is something wrong with you python code.

The code for parameter parsing must be fine, otherwise the tests wouldn't have passed. Perhaps the issue arose after the workflow was turned into a tool, and then nodes were modified within the workflow. Today, I encountered a malfunction with the if-else nodes as well; the problem was resolved after removing the tool.
