setPlaybook + Post-Processing

[NivNet]

Hi everyone,

I have a Post-Processing script that uses the setPlaybook command to switch the incident to a playbook called test1.

The problem is that when I close the incident, the script doesn’t run just once - it keeps setting the same playbook repeatedly, and as a result the test1 playbook is triggered about 10 times in a row.

Here’s my code:

try:
# Run the test1 playbook
result = demisto.executeCommand("setPlaybook", {"name": "test1"})
return_results(True)
except Exception as e:
return_error(f"Error: {str(e)}")

My question is:
How can I make sure the playbook is set only once, and avoid it running multiple times during closing?

Thanks in advance!
