I have a custom web tool that I am using in the new Analysis Widget. It has an input parameter that is layer. I set up the widget to include a web map with the layer I want user to use as the input, but when I try to use the tool nothing happens when I click the "+ Layer" button. It just says the input is required. If I use a built-in Spatial Analysis Tool, the "+ Layer" button allows me to select the layer from the map.
