Universal Linking Serving AASA File

Please provide the following:

  1. SDK Version: 40
  2. Platforms(Android/iOS/web/all): all

I’m having some trouble with the AASA file and configuration for universal linking. I have my AASA file here and my app.json includes the following:

"associatedDomains": [
        "applinks:*meetcollie.com",
        "applinks:meetcollie.com",
        "applinks:*collie-web.herokuapp.com",
        "webcredentials:*meetcollie.com",
        "webcredentials:*collie-web.herokuapp.com"
  ]

However, this fails the AASA validator check with the following:

I currently have my AASA contents stored in the front-end with the React code so my understanding is that’s the issue. My confusion is how exactly do I render the AASA file? The expo docs mention that this file needs to be served from your webserver, so what are the steps needed to do this? Also is there a way to do this from the backend?
