Webstorm throws an error for mocha describe function

I have a very simple code to create a mocha test. But It doesn't give any warning that it doesn't recognize 'describe', but when I run the test it throws error saying "TypeError: describe is not a function". Interestingly, yesterday all my test cases were running, and nothing has changed since then. This morning I just opened webstorm, ran the tests and getting this error.

I've tried to look for answers online but haven't really found an answer yet.

Here is my code:

console.log('msg');
const { describe, it } = require('mocha');

console.log('msg2');
console.log(typeof describe);

describe('virtualagents', () => {
  console.log('desc');

  it('runs as expected', (done) => {
    done();
  });
});
