Here we need to make few changes
Like
InputArguments”: “{\“””greeting\”””:\”””Aloha\”””}”
That is surrounding double quotes with two double quotes when placed between double quotes
Kindly type in your expression and don’t copy the expression from because sometimes the double quotes symbol will get changed when copy pasting
That’s why
Hope this would help you
Kindly try this and let know for any queries or clarification
