Hi Harshith,

You could utilise the Utility - Environment VBO and invoke your Python script through the Arguments under Start Process Action.

Hi Jegendra,

Can I get output from that python script onto blueprism using your method?

Thanks.

Hi Harishith,

Using the Action (Start-Process) would not give you any outputs.
Output needs to be written into a file, and the file subsequently read.

Alternatively, you could investigate and experiment writing your own code stage.
Or expose your python script as web service and then invoke the web service into Blue Prism to retrieve the output value.

Use Start Process Read Stderr and Stdout of Utility - Environment output will be read to Std Output dataitem.

Hi Gopal,

Could You Elaborate on your solution, please?

Coz I'm not able to find Read Stderr and Stdout

Thank you

You probably have an older version of the Utility - Environment VBO.

I think the one that gets Standard Output and Standard Error was packaged with one of the V6 Blue Prism versions. Maybe 6.3 or so? I'm not sure.

You can download this one from the Digital Exchange. It has the action 'Start Process Read Stderr and Stdout' in it: https://digitalexchange.blueprism.com/dx/entry/9648/solution/blue-prism-environment

Yeah, Dave, you're right.

I have an older version.

Hi Dave,

Can you please share the above link again. Because I am using BP V6.10, but I can't find the Action 'Start Process Read Stderr and Stdout'.

Thanks

If you login to the digital exchange digitalexchange.blueprism.com and then search for "utility environment", it should show up as the first result as well.
