I have a calendar in my app that can be navigated using either the dropdowns to select a month/year (which works) or the arrows to navigate forward/backward between months. When I first created this screen, clicking the arrows worked to navigate the calendar.

Now, a day later, when I click the arrows the app gets stuck on a white screen and I get the following error in the console when running the app in the browser:

The arrows are simply setting a variable and then selecting a hidden button (visible but behind the header) to have it recalculate the data for the calendar
