Add this code to your additional-methods.js file.

$.validator.addMethod('fileSize', function (value, element, param) {
    return this.optional(element) || (element.files[0].size <= param)
}, 'default message');

Running your code, I see the following exception being thrown:

Exception occurred when checking element , check the 'extension' method. TypeError: Cannot read property 'call' of undefined

It seems like the extension method isn't included in the validate plugin by default. It's a separate script you need to include in your html.

Including <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/additional-methods.js"></script> fixed it for me.

Browsing the documentation of the jQuery validation plugin, I didn't see a method for filesize. See https://jqueryvalidation.org/jQuery.validator.addMethod/ to create one yourself. Should be straightforward.

For example:

jQuery.validator.addMethod('filesize', function (value, element, arg) {
  // value -> name of the file being uploaded
  // element.files[0].size -> size of file being uploaded
  // arg -> 2048
  // Do some validation of filesize and return true or false
});
