Setting Up CORS

When self-hosting, you may run into a CORS error when trying to run your app on https://localhost:3000. If you do, you will need to ensure that you have set https://localhost:3000 as an allowed origin on your server.

To do so, you will need to add it to the allowedOrigins field on your server config settings. By default, the only allowed origin is [apiBaseUrl].com, but you can add more in a comma-separated list. For more details, see the Config Settings docs.

Allow All Origins

To give all origins access to make CORS requests, you can use the special allow all case by setting: allowedOrigins: '*'.
