This error is showed up when I ran the code for an Arkanoid Game published on freecodecamp articles. I am not able to set up the configuration correctly for the game. I expected it to run the game but it didn't do the same. While debugging it kept throwing errors regarding its build. I have no idea as I have learned it online but this error is not getting resolve. I am attaching both the debugger image and the error image along with the log file text, where it showed the error. DEBUG CONSOLE

The above codes are the mainframe of the game. Hope it helps to resolve.
To be able to load an ES module, we need to set “type”: “module” in this file or, as an alternative, we can use the .mjs file extension as against the usual .js file extension.
In your package.json file add this:
{
"type": "module",
}
For an example:
{
"name": "esm",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"type": "module",
"author": "",
"license": "ISC"
}
If this doesn't work uninstalling both global and local versions of parcel:
npm uninstall parcel
npm uninstall -g parcel
Then install it using this command:
npm install parcel --save-dev
