Cannot Access Resource on Gitlab Pages

I have seen some issues posted about this, but none seemed to have a detailed resolution.

I currently have a webpage up at https://jvanderen1.gitlab.io/restaurant-and-food-inspections-visualization/

From this page, I am using fetch to make a request to the following endpoint: https://jvanderen1.gitlab.io/data/alaskaGeoData.json

However, I am getting the following error:

Access to fetch at 'https://projects.gitlab.io/auth?domain=https://jvanderen1.gitlab.io&state=ByVTWy6Yb6wc1SqWVdlrOQ==' (redirected from 'https://jvanderen1.gitlab.io/data/alaskaGeoData.json') from origin 'https://jvanderen1.gitlab.io' has been blocked by CORS policy: 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.

Do you guys have any suggestions? Thanks.
