CORS error on flutter web when sending events

[johannesstricker]

Hey, I wanted to try aptabase for flutter web, but events cannot be sent to the server due to CORS issues.

Access to XMLHttpRequest at 'https://eu.aptabase.com/api/v0/events' from origin 'http://localhost:5001' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

As you can see, I'm running locally on port 5001. I tested this against self-hosted and managed aptabase and got the same problem with both. Is this a known issue? I thought that aptabase accepts any origins by default.
