Hello,
I have a simple workflow with two “Execute Python Script” steps.
In the first, a list called data is created with some integers and in the second Python Script I am iterating through the list, applying a mathematical operation to each element in the list.
But when I run this workflow for the first time, I get an error “NameError: name ‘data’ is not defined” in the second Execute Python Script. The variable data is defined in first Execute Python Script.
When I run this workflow again, for the second time, it runs without any error.
Is this the expected behavior? Is there any way to run this workflow without errors everytime?
How can I catch this and another exceptions to handle externally, if Execute Python Script step does not have an Error handling hop?
First Execute Python Script code:
# python script
data = [1, 2, 3, 4, 5]
Second Execute Python Script code:
# python script
squared_data = []
for item in data:
squared_data.append(item*item)
The error message:
