Error in the Python Scope Activity

@didac.elguet, Try running this sample code. You should have .Net runtime 6.0 installed and the Python exe path added to System variable. Main.xaml (8.3 KB) Thanks, Ashok

check this thread as reference

@victoryv4569,

Is your python path added to environment variable? Check this once.

Try this sample code. It’s on higher version but try changing it as per your setup.

Ran the same code in python its given the output, but in UiPath got an error

An Error was,

@victoryv4569,

I would suggest to create new thread for this so this new issue will get noticed by the experts.

Back to your issue, as per this thread it happens when your script returning big size data. The size could vary as per system config but this is the most probable reason.

Invoke Python Method: Pipe is broken

Hi @VC365, Pipe is broken is a very abstract error in .net and C# and with minimal root cause. I have wasted a lot of time trying to find out why this happens without a concrete answer in the forums or in stackoverflow. In my view, the amount of data being sent from one activity to another or one workflow to another throws “Pipe is broken.” error in UiPath. I suspect that your python code returns an object (json, og other object from python to .net) which is of a large size. What is large? I…

Other option you have is, if you could working folder of python scope to store the output in some file and read it back wherever required in your code again.

Thanks,
Ashok
