I am a beginner with the angular framework. I need to populate a drop in my component. The elements will come from a feature layer. The drop down needs be populated in the beginning to work or I guess I could subscribe to a method. I created a service that should return a promise so and on the element I believe I am subscribing to the method. However I am having issues with returning a promise in the service. Can you guys tell me how I should change the service to return the promise I need or if there is a better way to do it? I am using Angular 9, and the esri loader I think it is the latest because I used the command npm install --save esri-loader to install it, although my package.json lists the 2.13.0 version. Thank you for any help!

Hi, I need to know the scale of an mxd in a web application. For that I am running  a geoprocessing service. I need to know the scale when there is a definition query and the map zooms in to that feature. I can see in the message that the scale changes, but the output in the web application is always the same scale, although the input feature changes. What am I doing wrong?
