Issue
Events sent by the SDK get a 403 response from the server with the message:
{"detail":"event submission rejected with_reason: Cors"}
Applies To
- All SaaS Customers and Self-Hosted Users
Resolution
Ensure the list of allowed domains contains all the origins/referrer domains used by your application. You can follow the steps below:
- Open the network logs in the browser
- Go to a page in your app that triggers an event, and subsequently the 403 response
- Open the request that is getting the 403 in the network tab
- Under "Request" headers find the Referrer header
- Add the domain of the referrer header to your list of "Allowed Domains" in the Sentry Web UI project settings
