CORS Error when setting up AuthMe API in AppGyver Data Configuror

I am trying to set up user authentication tokens in AppGyver but when I try to pull a test, I receive the following response.

Error: TypeError: Failed to fetch. Does the server allow CORS?status: undefined

I have had no trouble up to this point setting up authentication using Xano to this point so I am quite confused on what is happening. The API is also working when testing in Xano.

Thank you for your help in advance.
