Thanks for trying out connectors! The CORS error is between your browser and the Router, so I’ll refer you to the [router docs on CORS](https://www.apollographql.com/docs/graphos/routing/cloud/configuration#cors-settings).

Are you using Sandbox from [http://localhost:4000](http://localhost:4000), or from [Studio](https://studio.apollographql.com/sandbox/explorer)? The latter definitely requires changing your Router’s CORS settings, while the former is on the same host so it doesn’t require changing anything.

In you router-config.yaml you can allow any origin which will mitigate the CORS error:

```auto
cors:
  allow_any_origin: true

```
