How to import a Glitch Assets folder image for a Phaser 3 external javascript file named sceneMain.js

I’m working with Phaser 3, Node.js, Express and the photonstorm phaser3-project-template (phaser3-project-template - npm).
This template allows use of ES6 and Webpack (which may be a deprecated version like Webpack 3 as I’m getting a lot of Node.js/npm deprecated file messages)
I have the template working with an image from the Glitch assets folder rather than from the provided src/assets folder but can’t seem to get the code to work for a modular external sceneMain.js file in the src/scenes folder. I thought I had it working once, but I changed something and don’t remember how I coded it to make it work and I’m not sure at what point in rewind the import code was working to rewind to.

The preview takes quite a long time to display so I wonder if Webpack is properly configured or the template is interfering with the Glitch auto reloading.

The error in the logs seems to be about a path setting.

Child html-webpack-plugin for “index.html”:

  1. Using Glitch there seems to be a need to put a comment regarding globals on the top line (not sure this is currently correct for ESLint) e.g. // global Phaser, sceneMain.js
  2. tutorials usually have a line in index.js to import an image from a path and file but I’m not sure how this should be coded with the Glitch Assets folder CDN URL.
  3. putting ‘export default SceneMain;’ at the end of sceneMain.js seemed to work the first time
  4. With ES5 I have to put external javascript filenames in a script file in index.html in the head or body. Doesn’t seem necessary for ES6.
    index.js

// global sceneMain.js
