Custom Nerdlet works for some users in my organization, but not others with the same permissions

Hello, I’ve been having some issues with a custom nerdlet I deployed. Mainly, some users are able to access it with no problem, but others users with the same permissions experience a crash as soon as it loads. I was wondering if anyone has run into an issue like this in the past.

When it crashes, the two main errors I see are “Uncaught TypeError: Cannot read property ‘filter’ of undefined” and “Uncaught TypeError: Cannot read property ‘sort’ of undefined”, both coming from the nerdlet (.js file) and not the actual code.
