I am trying to run an API test for getting the version using Chai. I have this test in a version.tests.js file inside the src/tests folder. I am using “mocha ./src/tests/**/*.tests.js” to run it.

For some reason I get this error when running the command above:

Exception during run: version.tests.js:1
import chai, { expect } from "chai";
       ^^^^
SyntaxError: The requested module 'chai' does not provide an export named 'default'

My version.tests.js file looks like this:

import chai, { expect } from "chai";
import chaiHttp from "chai-http";
import app from "../app.js";

chai.use(chaiHttp);

describe('Version API', () => {
    it('should return the correct version', async () => {
        try {
            const res = await chai.request(app).get('/api/version');
            
            expect(res).to.have.status(200);
        } catch (error) {
            throw new Error(error);
        }
    });
});

The packages version are:

“chai”: “^5.1.1”, “chai-http”: “^4.4.0”, “mocha”: “^10.4.0”

Does anybody know why this is happening? Thanks!
