Inspect Chai Assertion error returning [Object] [Object]

Question

I have a test

    let resultRedirects = {
        redirects: {
            fromPaths: [
                {
                    path: '/a-good/path',
                    type: 302
                },
                {
                    path: '/goodpath/Rocky%20Mountain%20PBS-HD,%20Create%20and%20V-me.',
                    type: 301
                }
            ],
            toPath: '/shows/default'
        }
    };
    let someFunc = sinon.stub();
    let wrapper = shallow(<Settings {...props} />);
    wrapper.instance().someFunc2({
            target: { value: '302' }
        },
    0);

    expect(someFunc).to.have.been.calledWith(resultRedirects);

The SomeFunc2 content is:

changeRedirectType = (e, index) => {
    const {
        redirects,
        redirects: { fromPaths },
        path
    } = this.props;
    let redirectsFromPaths = [...fromPaths];

    redirectsFromPaths[index].type = parseInt(e.target.value);

    changeSettings({
        redirects: {
            ...redirects,
            toPath: path,
            fromPaths: redirectsFromPaths
        }
    });
};

The response is

AssertionError: expected stub to have been called with arguments {
  redirects: { fromPaths: [ [Object], [Object] ], toPath: '/shows/default' }
}
{
  redirects: { fromPaths: [ [Object], [Object] ], toPath: '/shows/default' }
}

How can I inspect inside [Object] [Object] ?
