Hi @RaviPalanisamy,
In my example i use “Form” action and in your case you use “Form” trigger.
They have the same strucutre but access data depending form type and steps.
For example if i test to access a variable of trigger form :
In your case you must use the following configuration :
{"serviceAccountName.$" : "$.trigger.formData.serviceAccountName"}
Let me know if it’s ok.
