Getting this error:

[!] (plugin rollup-plugin-iife) TypeError: The "path" argument must be of type string. Received undefined
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

I'm using it like this:

output: [
            {
                file: "build/demo.js",
                name: "demo",
                format: "umd",
                globals: {
                    document: 'document',
                    window: 'window'
                },
                externals: ['document', 'window', 'Math'],

                plugins: [iife()]
            },
            {
                file: "build/demo.min.js",
                name: "demo",
                format: "umd",
                plugins: [terser(terserOptions)],
                globals: {
                    document: 'document',
                    window: 'window'
                },
            },
           
        ],

This plugin converts esm into iife so you have to change format: "umd" to format: "esm".
