Universal link - The domain has some validation issue

Question

Im working on universal link to open the application while tap the url. I am using https server and done all the steps from apple (Apple Doc). But the apple universal link validator show below error,

Your file's 'content-type' header was not found or was not recognized.

enter image description here

The apple-app-site-association file successfully uploaded to server and the file be like below,

{
    "applinks": {
        "apps": [],
        "details": [
            {
                "appID": "J2HBF9A3PZ.com.aors.speaku",
                "paths": ["*","/"]
            }
        ]   
    }
}

And apple said no need to sign the apple-app-site-association file whether the domain has https.

If the file is unsigned, it should have a Content-Type of application/json. Otherwise, it should be application/pkcs7-mime.

So my query is how to mention the content type (application/json) in this apple-app-site-association file???

please help me on this. i don't know what it mean exactly.

have you ever figured this out? I'm having the exact same issue here. — David, Oct 24 '16 at 15:53

I just solved this issue myself. I had to logon to my server and go to the directory where the apple-app-site-association file was. In this directory, I had a .htaccess file which I modified to include the following lines:

<Files "apple-app-site-association">
ForceType 'application/json'
</Files>

After doing this, the validation service stopped complaining about the Content-Type.

NOTES:

If you don't have a .htaccess file, you can just create one.
I presume the .htaccess file should be in the root of your site directory (which is where you would most likely have placed your apple-app-site-association file.

I have followed the above steps, still stuck. When I validate on branch/io, it is giving me errors. - Your server returned an error status code (>= 400). This includes client side and server side errors. Want to know what this means? Click here. - Content type test did not run. Be sure to define a ‘content-type’ header. - JSON test did not run. Your file should contain valid JSON. – Rajesh Nov 16 '18 at 12:35

I have the same problem. can't resolve the content-type problem – Mahdi Shabani Jan 05 '19 at 15:22
Same issues... I dont know whats the problem. I added your .htaccess but got : Your server returned an error status code (>= 400). This includes client side and server side errors.

If anyone else comes upon this... I tried lots of solutions and this one didn't work for me either... the only one that did was adding this to my .htaccess: `RewriteRule ^apple-app-site-association$ - [env=apple:1] Header set Content-type application/json env=apple` – Britton Pentakill Sep 22 '19 at 18:30
best solution , I spent 6 hours on why domain has validation issue – Dharini Jan 22 '20 at 10:24

This one fixed the content type validation in firebase.json file.

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

Wordpress website. Pasting this at the end of .htaccess actually worked for me:

Header set Content-type "application/pkcs7-mime"

At the end of the .htaccess file: ``` ... # Begin DeepLinks - Ophir Header set Content-type "application/pkcs7-mime" #END DeepLinks ... ``` – Ophir Stern May 04 '20 at 05:31

This syntax is what worked for me:

<FilesMatch "apple-app-site-association">
    ForceType application/json
</FilesMatch>
