UnhandledPromiseRejectionWarning: Error: Unsupported MIME type: image/x-icon

I use this package both in dev and prod environment. I have similar set up but I get this error in the production. it is fine in dev.

here is the webpack set up

const FaviconsWebpackPlugin = require("favicons-webpack-plugin");
const pathToFavicon = path.join(__dirname, "../../favicon.ico");

plugins:[
    new FaviconsWebpackPlugin(pathToFavicon),

]

I m getting this error only in prod.

this is the webpack.dev vs webpack.prod
