Error resolution for fibers not supporting Node.js 16

Summary of Issue

It has been reported that the fibers package does not work properly in Node.js version 16. As a result, errors may occur and Node.js applications may not work as expected.

Solution.

Currently, the recommended solution is to downgrade the Node.js version to 15 or lower; tools such as nvm (Node Version Manager) can be used to manage the Node.js version.

nvm install 15 
nvm use 15

This will change the Node.js version to 15 and allow the fibers package to work properly. However, lowering the Node.js version may prevent the use of new features, so careful consideration should be given before applying this solution.
