Error in invoking python code: "pipeline is broken"

[henry.wang]

Hi all,

I have received help to develop a python script which is used to extract information from a pdf file. The python code runs fine when run from cmd, but does not function properly when run from UiPath activities.

This is the python code:

def test(file_path):
from biokraft import app
import os

file_type = "xxx"
return_type = "json"

parsed = app.parse(
    file_path=file_path, file_type=file_type, return_type=return_type
)

return parsed

If I just input some random pdf, it will run through the process and give empty values:
But if I actually input the correct file for which I want to extract the information, I would get the following error:

System.IO.IOException: Pipe is broken. at System.IO.Pipes.PipeStream.CheckWriteOperations()
at System.IO.Pipes.PipeStream.Flush()
at System.IO.StreamWriter.Flush(Boolean flushStream, Boolean flushEncoder)

at System.Activities.Runtime.FaultCallbackWrapper.Invoke(NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)
at System.Activities.Runtime.FaultCallbackWrapper.FaultWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

Anyone know how to proceed here? Please advise

Hi @henry.wang

Check the below thread

Latest Support For Python 3.12 And Python.Activities Version Update

Hi @Babar_Awan The Python package does not support Python 3.12 just yet, but the upcoming next version will. We hope to release it this month.

I am using Python 3.9 for this, so it’s not a version issue

Hi @henry.wang

Pipe is broken

@muhammedyuzuak Thank you, your post guided me to the problem. When i was installing package in my PyCharm IDE it was installing only localy, so there was nothing installed inside: C:\Users\User2\AppData\Local\Programs\Python\Python38\Lib\site-packages Therefore uipath were throwing “pipe is broken” error. I have installed packages required for project using windows command line and it installed finally packages where i wanted. Now i can run my python script. Marking as solved.

While Invoking python code using python package, am getting Pipe is broken error!

Hi @Athul_AK, Check your UiPath Python package configuration: Ensure that you have installed the latest version of the UiPath Python package and that it is configured correctly in your UiPath project. Verify that the Python interpreter path and the Python script path are correct. Check the Python code: Review the Python code that is being executed in UiPath. Make sure that the code is well-formed and does not contain syntax errors that could cause issues with the Python interpreter. Also, ver…

1、Change the Python Version 3.6 2、Change the uipath.python.activities 1.3 Try it~

I’ve already tried those solutions, none of them seems to work. Any other suggestions?

@henry.wang

1. Just to check if issue with python can you run any dummy python sequence and check
2. Is it failing on running only?

Cheers

Hi Anil. Yes the python code runs fine from cmd. It’s failing on running only.

[Anil_G (Anil Gorthi)]

@henry.wang

Did you run a small code to check if that is working?

Also as next steps check the event viewer logs to understand if there is an issue

event viewer logs will have more info about the pipe broken error

cheers
