all.

I have JS code that works in a Shiny App but no longer works when I call it in a module. I assume this problem has to do with name spaces, but I'm at a loss. Help would be greatly appreciated.

Works when not in a module:

actionButton('download_try_2', "Download Plot"),

mainPanel(plotlyOutput("wv_test", height = "650"),
                                     
tags$script('document.getElementById("download_try_2").onclick = function() {
                                     var gd = document.getElementById("wv_test");
                                     Plotly.Snapshot.toImage(gd, {format: "png"}).once("success", function(url) {
                                     var a = window.document.createElement("a");
                                     a.href = url; 
                                     a.type = "image/png";
                                     a.download = "plot.png";
                                     document.body.appendChild(a);
                                     a.click();
                                     document.body.removeChild(a);
                                     });
                                     } ')

When I try:

actionButton(NS(id, 'download_try_2'), "Download Plot"),

mainPanel(plotlyOutput(NS(id, "wv_test")),

tags$script('document.getElementById("wv_test-download_try_2").onclick = function() {
                                     var gd = document.getElementById("wv_test-wv_test");
                                     Plotly.Snapshot.toImage(gd, {format: "png"}).once("success", function(url) {
                                     var a = window.document.createElement("a");
                                     a.href = url; 
                                     a.type = "image/png";
                                     a.download = "plot.png";
                                     document.body.appendChild(a);
                                     a.click();
                                     document.body.removeChild(a);
                                     });
                                     } ')

I get the error:

Error in htmltools::validateCssUnit(width) : CSS units must be a single-element numeric or character vector
