Trouble with normalUtils/normalizeCentralMeridian()

[MansiShah]

Hello,

I am trying to use the normalizeCentralMeridian method to normalize the coordinates over dateline. I have the following code:

var rings = JSON.stringify(evt.geometry.rings);

var genoms = new Extent(evt.geometry.rings);  //I have also tested making genoms of type new Geometry with the same //outcome

console.log("genoms: ", genoms);

console.log("before normalizeUtils.normalizeCentralMeridian()");

console.log(normalizeUtils.normalizeCentralMeridian(geoms);

evt.geometry.rings is an array object. Printing it out gives me the following: 

[[[-232.56299422870526,37.89843860927253],[-232.35205659066006,37.89843860927253],[-232.35205659066006,37.766602669313315],[-232.56299422870526,37.766602669313315],[-232.56299422870526,37.89843860927253]]]

Printing out genoms gives me the following:

1. 1. Array(5)
      1. 0:(2) [-231.97361670477855, 37.030176591569784]

       7. vcsWkid:undefined
       8. wkid:4326
       9. wkt:(...)

**ignore the changes in the x, and y coordinates, I had to draw the area of interest on the map again after refreshing the application**

I want to be able to normalize the coordinates so I wanted to use the normalizeCentralMeridian() method (normalizeUtils | API Reference | ArcGIS API for JavaScript 4.6) but I get an error on the 3rd line of the code above with the message: 

before normalizeUtils.normalizeCentralMeridian()

Uncaught TypeError: Cannot read property 'wkid' of undefined

When you look at the reference page for normalizeUtils, it can take an argument of type Extent because it is a subclass of type Geometry. the wkid property is part of the SpatialReference object but even if I add a wkid property (by doing genoms.wkid = 4326) I get the same error as above.

Has anyone else encountered this issue and can help. Thank you so much!
