Android deeplinks aren't being registered, browser loading URL

I'm trying to have my android app open any urls that are at ex. mysite.com/users/12345 with an activity called LinksActivity, then (for now) just log everything in the intent. Instead when I send the test URL via android studio or open the URL in the browser it just loads the 404 for that page.

I have added the .well-known/assetlinks.json file to my site, and I'm not certain I got the SHA keys right, but I don't think that's the issue since when I change the URL to some URL nobody owns, it doesn't work that way either. And it doesn't work on the debug or the release versions of the app.

mysite.com/.well-known/assetlinks.json

[{
    "relation": ["delegate_permission/common.handle_all_urls"],
    "target" : { "namespace": "android_app", "package_name": "org.site.mypackagename",
                 "sha256_cert_fingerprints": ["The SHA for the Release Package is here"] }

                      "sha256_cert_fingerprints": ["The SHA for the Debug Package is here"] }
       }]

I needed to make sure my debug key was added to my assetlinks.json, and enable autoVerify=true.
