Need a null check or exists check for this Mutiple vs single typeof

[image]

I think I need another check to see if this node actually exists in the json or payload. I have tried hasOwnProperty() and hasPath()

Any other suggestions?

typeof ['wd:Submit_Published_Course_Section_Request']['wd:Published_Course_Section_Data']['wd:Course_Section_Data_Data']['wd:Published_Instructor_Roles_Reference'] == "array" ? jsonPath(, “['wd:Submit_Published_Course_Section_Request']['wd:Published_Course_Section_Data']['wd:Course_Section_Data_Data']['wd:Published_Instructor_Roles_Reference'][*]['wd:ID']['’]”):sl.ensureArray(['wd:Submit_Published_Course_Section_Request']['wd:Published_Course_Section_Data']['wd:Course_Section_Data_Data']['wd:Published_Instructor_Roles_Reference']['wd:ID']['’])

Resolved this on the custom SOAP envelope to see if the array is null.

!= ‘[null]’)
