I’m trying to implement live-update API on our pages, however Chrome is not happy, and cancels the request due to CORS.
When checking the request response, Access-Control-Allow-origin is set to *.
Running from Localhost there are no problems, and the error is only shown on our test environment.
The following error is shown in console:
Access to fetch at 'https://graphql-listen.datocms.com/channels/ce78c63b-9f42-4e6c-a13e-be42ac5c63df' from origin 'https://example.azurewebsites.net' 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. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
Have you seen this behavior before, or can I do something to fix et?
Thanks in advance
