Problem with edit issue functionnality automation

[Alexandre_Pate]

Hello.

I have a problem with the edit functionnality in automation. 

I want to automatically add watchers when a ticket is created. I have created a rule , which return no error in my .

cf[10881] is the id of my custom field "Watcher" (download in the JIRA plugins and set correctly in my project). Also tried with issue.watchers parameter, but not sure if this is correct

However, the field is not update in my issue.
As I have no information in the loggs, i'm totally lost.

Can you help me ?

Thanks

Alexandre Paté

Found the problem, cf[10881] seems not to be correct.
Replace it by customfield_10881
