Trying to assert a date format in Cypress that has white space

I am trying to write an assertion in my Cypress test that checks that the date format is mm/dd/yyyy.

Right now, the assertion is failing and I think it's because there is white space at the start and end of the date, as you can see below.

To extract the value from the HTML, I used an alias. When I hardcode the date and use contain instead of match it passes, but when I use Regex instead and use match it fails.

How can I deal with white space when writing an assertion?

I am testing this using Cypress on a web app built in Angular.

HTML

<mat-cell class="mat-mdc-cell mdc-data-table__cell cdk-cell cdk-column-Test-Date mat-column-Test-Date ng-star-inserted" role="cell"> 10/10/2024 </mat-cell>


Cypress Test

cy.get("cdk-column-Test-Date").as("testDate");
cy.get("@testDate").should("match", /^(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d$/);
