Solve 'require(...).create is not a function' Error in Node.js with simple-oauth2

The error 'require(...).create is not a function' usually occurs when you are using an incorrect syntax to require a module that has a create function. Here are a few steps you can take to resolve this error:

1. Make sure that you have installed the simple-oauth2 package using npm. You can do this by running the following command in your terminal:

npm install simple-oauth2

2. Check the documentation of the module you are trying to use to see if it has a create function. In the case of simple-oauth2, the create function is used to create a new OAuth2 client. You can declare the create function by using the following syntax:

const { create } = require('simple-oauth2');

3. Make sure that you are using the correct version of the module. If you are using an old version, the create function may not be available. You can check the version of the module in your package.json file.

4. If none of the above steps help, try deleting the node_modules folder and reinstalling all the packages using the following commands:

rm -rf node_modules
npm install

This will reinstall all the packages in your project, including simple-oauth2, and may resolve the issue.
