Description

Hi,
I'm getting multiple CORS errors on my electron react app for windows when using react-map-gl.
The map is actually loading fine and seemingly working fine as well, but my log shows these errors:

Access to fetch at 'https://events.mapbox.com/events/v2?access_token=TOKEN' from origin 'http://localhost:1212' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
AND
mapbox-gl.js:31 POST https://events.mapbox.com/events/v2?access_token=TOKEN net::ERR_FAILED 204

Any idea how to solve this? I can't change the request's mode to 'no-cors' as recommended by the error, since the request is done by the react-map-gl lib.

When trying to enable 3D Terrain, I'm getting similar errors constantly and most of the time the 3D Terrrain is not working

Environment

  • Framework version: 9.6.7
  • Map library: 9.6.7
  • Browser: Electron

The error is from mapbox-gl, you should ask in Mapbox's repo.
