Javascript keeps sending same error ID and returns a 403

When using the JS Sentry SDK for our company’s React project, I keep getting the same error when trying to send an error to Sentry. The call to Sentry keeps using the same error ID (00000000000040008000000000000000) and returns a 403 Forbidden with this body:

“error”: “An event with the same ID already exists (00000000000040008000000000000000)”

Does anyone have any idea whats going on here/how to fix it? For context, our React app is was made using create-react-app. But then when we tried to reproduce this issue on a new CRA project it worked, so I was wondering if it has to do something specific in our original project. Any help is appreciated here, thank you.
