mediasoup is undefined node.js

I am using mediasoup library to create video calls with many people in one room. Having imported npm package, it gives me a message that it is undefined:

async createWorker() {
this.worker = await mediasoup.createWorker({
  rtcMinPort: 2000,
  rtcMaxPort: 2080,
});
logger.debug(`worker pid ${this.worker.pid}`);

this.worker.on("died", (error: any) => {
  // This implies something serious happened, so kill the application
  logger.error({
    error: error.toString()
  }, "mediasoup worker has died");
  setTimeout(() => process.exit(1), 2000); // exit in 2 seconds
});

}

the error:

    C:\Users\andri\Desktop\resume_projects\college_chat\back\src\messaging\socketManager\index.ts:22
    this.worker = await mediasoup.createWorker({
                                  ^

My node version: v18.17.0 My python version: 3.10.7 I have MSBuild tools installed since I have visual studio on my laptop (I am on Windows). I have also tried to install this package as administator from a separate terminal - didn't work as well.

mediasoup here is imported by its default value, when it does not export a default value (undefined). createWorker is defined as a named export. You can either import all named exports as a variable import * as mediasoup or import just createWorker import {createWorker}.

The package was installed successfully because if you was importing an invalid package, it would've thrown a "Cannot find module" error.
