Firebase Hosting for apple-app-site-association

firebase.json

{
  "hosting": {
    "headers": [
      {
        "source": "/.well-known/apple-app-site-association",
        "headers": [{"key": "Content-Type", "value": "application/json"}]
      }
    ]
  }
}

SOLVED my folder was .well_known instead of .well-known

I don't know why I am getting content-type: text/plain; charset=utf-8 when curl -i https://destrompesetvous-b6900.web.app/.well_known/apple-app-site-association

I also placed apple-app-site-association inside root and here it is working, I am getting content-type: application/json when curl -i https://destrompesetvous-b6900.web.app/apple-app-site-association

firebase.json

{
  "hosting": {
    "public": "build/web",
    "headers": [
      {
        "source": "/.well-known/apple-app-site-association",
        "headers": [
          {
            "key": "Content-Type",
            "value": "application/json"
          }
        ]
      },
      {
        "source": "/apple-app-site-association",
        "headers": [
          {
            "key": "Content-Type",
            "value": "application/json"
          }
        ]
      },
      {
        "source": "/.well-known/assetlinks.json",
        "headers": [
          {
            "key": "Content-Type",
            "value": "application/json"
          }
        ]
      }
    ],
    "appAssociation": "NONE"
  }
}

apple-app-site-association and .well_known/apple-app-site-association

{
  "webcredentials":{
     "apps":[
        "JJS627SP9W.fr.trompe.appli"
     ]
  },
  "applinks":{
     "details":[
        {
           "appID":"JJS627SP9W.fr.trompe.appli",
           "paths":[
              "*"
           ],
           "appIDs":[
              "JJS627SP9W.fr.trompe.appli"
           ],
           "components":[
              {
                 "/":"/*"
              }
           ]
        }
     ]
  }
}

And tried adding rewrites rules without success

"rewrites": [ {
      "source": "/.well-known/apple-app-site-association",
      "destination": "/apple-app-site-association"
    } ],
