I am trying to create a workflow as shown in the below image. I need help with “Function Node” before the email. To give a brief background, the workflow starts with getting Date and Time and then 3 execute cmd nodes get executed. Each of these executes cmd node run’s a python script then Status Checker checks if the exit code of all 3 parent nodes and if one or more executes cmd node fails then the false part will get kick-off were i am using function node to get the names of the failed nodes set the name as a string. for exam if Run-1 and Run-2 is failed the that function should set a string “Run-1, Run-2” and then this string of failed node name get sent via email.
I am having trouble dynamically getting the name of failed nodes. I want an approach where if I add one more execute cmd nodes in the future then I don’t have to modify this function.
