Unable to capture errors in React

Hi. I’m developing an application in React redux.

I’ve read the documentation for React (https://docs.sentry.io/platforms/javascript/guides/react/) and I’ve seen that the error appears in the Sentry admin panel as well.

However, there is an error that is occurring in the browser but not showing up in Sentry’s admin screen.

I tried setting tracesSampleRate to 1.0 and it didn’t show up.

What could be the reason for the error to appear or not appear?
