I looked at your template @Ilham Israfilov (thanks for including it), and I saw that your logic app depends on
OrderFunction. It appears your
OrderFunction doesn't have any binding associated with it. This could be what's causing the error message as the invocation of the function can't be determined. Have a look at diagnose and solve problems as it might provide some steps on how to remedy or maybe add the bindings to your template, see this sample template.
