Error: No "exports" main defined in /path/to/the/repo/node_modules/@middy/core/package.json

After updating middy/core and its connected packages (ex. middy/http-content-negotiation,middy/http-cors) from 4.x.x to 5.x.x encountered a new error during endpoint testing of Lambda handlers. Most likely an issue coming from the removal of support for CommonJS. For the lambda deployment I am using serverless.

const getListHandler = async (event, context) => {
  return {
                statusCode: 200,
                body: "Hello World"
            };
};

export const getList = middy(getListHandler)
    .use(cors())
    .use(httpSecurityHeaders());

Is this dup of #1208 ?
