Closest Facility Arcgis online javascript not returning data - arcgis

Question

I am trying to use the Closest Facility (CF) function in ArcGIS API for Javascript. I need to be able to pass a shape coming from a feature service as an incident, and use a feature service with multiple points as the facilities.
Currently when I use the Closest Facility task, nothing happens. No calls are made at all if I look at the network activity.
CFTask.solve(CFParams).then(function (solveResult) {
array.forEach(solveResult.routes, function (route, index) {
console.log(route);
});
});
I understand that i may be passing it incorrect data, but would expect an error message, rather than the nothing I get now.
2 questions:
Does the above code snippet actually run the Closest Facility
function?
How do add data from a feature service to a feature set correctly?

Answer 1

First, verify if an error is triggered inside the promise when you run the code snippet by using catch method:
CFTask.solve(CFParams).then(function (solveResult) {
solveResult.routes.forEach(function(route, index) {
console.log(route);
});
}).catch(console.error);
If you see an error message printed in the console, add it to your question.
Also there is a syntax error in your forEach function
