Error doesn't handle in the respond of the RequestMock

[Aleksey28]

What is your Scenario?

I have a code with an error in the RequestMock.respond.

What is the Current behavior?

If I don't make an error handler for my code there the test will hang.

What is the Expected behavior?

The test shouldn't hang

What is your public website URL? (or attach your complete example)

In this example, I only use API https://jsonplaceholder.typicode.com/todos/1

What is your TestCafe test code?

import { ClientFunction, RequestMock } from 'testcafe';

const mock = RequestMock()
    .onRequestTo('https://devexpress.github.io/testcafe/example/todo')
    .respond(async (req, res) => {
        let body = {};

        //try {
            body = await fetch('https://jsonplaceholder.typicode.com/todos/1').then(data => data.json());
        //}
        //catch (err) {
        //    console.log(err);
        //}

        res.headers['access-control-allow-origin'] = '*';
        res.setBody(body);
    });

fixture`RequestMock.onRequestTo`
    .requestHooks(mock);

test('Should mock requests', async t => {
    const jsonData    = await ClientFunction(() => fetch('https://devexpress.github.io/testcafe/example/todo').then(res => res.json()))();

    await t
        .expect(jsonData).eql({
            userId:    1,
            id:        1,
            title:     'delectus aut autem',
            completed: false,
        });
});
