How can you omit Lambda layers from being bundled in your Lambda functions? Is this supported?

import { myFunc } from '/opt/my-layer'

Hello you can do something like this

// eslint-disable-next-line no-undef
const {global} = __non_webpack_require__("/opt/config");

module.exports = {
  //...
  externals: [nodeExternals(), /^\/opt/, 'aws-sdk'] // exclude Lambda Layers
  //...
};
