Describe the issue

Hello, I have a library that I've compiled and I'm trying to run it in a ReactJS application.

This library uses AutoMapper with the classes strategy, and during startup, there are no compilation issues. However, once on the web console, the following error occurs:

Uncaught TypeError: classes_1.classes is not a function
    node_modules bundle.js:49154
    factory react refresh:6
    Webpack 39
mapper.ts:20
    js mapper.ts:20
    factory react refresh:6
    Webpack 39

The code in my library is similar (if not identical) to the documentation:

import {classes as classesFunction} from "@automapper/classes";
import {CamelCaseNamingConvention, createMapper, Mapper} from "@automapper/core";

export const mapper: Mapper = createMapper({
    strategyInitializer: classesFunction(),
    namingConventions: {
        source: new CamelCaseNamingConvention(),
        destination: new CamelCaseNamingConvention(),
    },
})

The result of the compilation:

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });

const classes_1 = require("@automapper/classes");
const core_1 = require("@automapper/core");
exports.mapper = (0, core_1.createMapper)({
    strategyInitializer: (0, classes_1.classes)(),
    namingConventions: {
        source: new core_1.CamelCaseNamingConvention(),
        destination: new core_1.CamelCaseNamingConvention(),
    },
});

Do you have any insights regarding this issue? Thank you in advance!
