I make a request that checks that the link in the footer has a 200 code, but the link to the LinkedIn page has a status code of 999. How do I add an exception to the test so that it works and checks that LinkedIn has a 999 status code

```
 private footerContainerLocator: string = '.footer';

    private get socialLinkList():Cypress.Chainable {
        return cy.get(this.footerContainerLocator).find('.social a');
    }
public checkSocialFooterLinks():void{
    this.socialLinkList.each((link) => {
        cy.request({ method: 'GET', url: link.attr('href'), failOnStatusCode: false }).then((response) => {
            expect(response.status).eq(200);
        });
    });
}

```
