Coordinate Conversion reverseConvert type issue

Char10773g

Hi, 

I am trying to follow this code snippet to add a new Format to the coordinate conversion widget. The problem I am having is that the reverseConvert property on the ConversionInfo type appears to be expecting a function with no arguments that does not return anything, but the example is passing a string and returning a Point.

The error is:

Type '(string: String) => Point' is not assignable to type '() => void'.

 

Has anyone come across this error before and found a workaround?

For anyone who is coming to this issue in the future - the reason for this issue is that the types are incorrectly defined in esri's interface.ts file. I have raised the issue with ESRI via premium support, and provided them with the correct type definition but incredibly they refuse to raise a bug to resolve it. I will post any workarounds if I come up with any.

For reference, this is the incorrect type definition currently in the interface file:

 /**
   * This object describes how a Format should be projected and formatted for display.
   *
   * [Read more...](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-CoordinateConversion-support-Format.html#ConversionInfo)
   */
  export interface ConversionInfo extends Object {
    /**
     * A function that takes a point and returns a [position](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-CoordinateConversion-support-Format.html#Position).
     *
     * [Read more...](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-CoordinateConversion-support-Format.html#ConversionInfo)
     */
    convert(): void;
    /**

     */
    reverseConvert(): void;
  }
