uploaded web build but live site is blank

[dj-designs]

Please run expo diagnostics and paste the log that’s printed out along with your question or issue!

• when I run expo build:web I see a directory called web
• but when I uploaded this to my demo server: Vital Tech Results - Improving User Experience With Automated Triggers the page is blank.
• then I ran yarn deploy after following these directions to upload web build to Github pages https://docs.expo.io/distribution/publishing-websites/ but this page is also blank: https://dominick-designs.github.io/react-native-app-ekadasi/
• yarn build set the settings in github (i.e. expo created a new branch and set the repo to a live site in Github settings.

I ran expo diagnostics and pasted the results here:
