Error cannot fetch app site association

Universal Link

i upload my 'apple-app-site-associationx' file to server.

Then i user the web site 'https://search.developer.apple.com/appsearch-validation-tool/' validator it.

there is the error message : 'Error cannot fetch app site association'

here is my 'apple-app-site-associationx' file's content :

{

"applinks":

{

"apps": [],

"details":

[ {

"appID": "4YPVN8PMEC.com.lexiangnetwork.sc",

"paths": ["/deaplink","/wwdc/news/","/videos/wwdc/2015/","*"]

}]

}

}

and my server domain is 'https://scbucket.oss-cn-beijing.aliyuncs.com'

which step is wrong? i need help

the same my probllem

Did you find any solution for this ?
I see this issue in iOS 13 also my json file in not updating. I have also checked my device logs its giving me previous downloaded json file.

Getting the same here :(
I believe it's just 'apple-app-site-association'

There is no 'x'
I think the 'x' is just a typo... same error for me. Validation on https://search.developer.apple.com/appsearch-validation-tool/ fails
Facing the same issue. The other problem here is that universal link keeps working one some devices, and not working on another with the same app version installed. Unfortunately can't share the specific OS versions

Tried few different formats:
  1. Based on the old one from here:

https://developer.apple.com/library/archive/documentation/General/Conceptual/AppSearch/UniversalLinks.html#//apple_ref/doc/uid/TP40016308-CH12-SW1

Code Block
{
"applinks": {
"apps": [],
"details": [
{
"appID": "9JA89QQLNQ.com.myapp.id",
"paths": [
"/launch",
"/help"
]
}
]
}
}


2. Based on the new one from here:
https://developer.apple.com/documentation/safariservices/supporting_associated_domains?preferredLanguage=occ

Code Block
{
"applinks": {
"details": [
{
"appIDs": [ "9JA89QQLNQ.com.myapp.id" ],
"components": [
{
"/": "/launch",
"comment": "Launch the app"
},
{
"/": "help",
"comment": "Open help"
}
]
}
]
}
}

In both cases used real app id with correct case sensitive formatting (not from the exmaple).

In both cases validation tool https://search.developer.apple.com/appsearch-validation-tool display next information:

Status: Action required. Could not extract required information for application links. Learn how to implement the recommended Universal Links.
Extracted Data : Error cannot parse app site association


Anyone found solution to this?
Same problem :(
Same. People have been asking about this for years, come on Apple! 😤
My advice for anyone else coming across this:

Ignore the Apple validator and check if it is working on a device.

In my case, I also had the "cannot fetch app site association" on the Apple validation tool, but it worked anyway on my device (the link redirected to the app).

If it's not working, there are a lot of possible reasons in this SO post.

The branch.io validator was also helpful for me.
